Research Summary
Three Numbers That Explain the Estimate
American Honda’s bulletin 20-047 instructs the shop to sand to a feathered edge with P240 or P320 paper, apply epoxy primer to bare metal, level with 2K primer, then apply basecoat and 2K clearcoat with a minimum 2-mil dry film build.[5]
American Honda recommends that basecoat thickness on bumper covers not exceed 40 microns on AcuraWatch 360 vehicles, and that total paint film stay under 300 microns, with 200 preferred.[9]
The NAIC’s Journal of Insurance Regulation reports that in practical claim settlement the diminished value loss ends up being roughly 10 to 20 percent of the direct physical damage loss.[12]
A Scratch Is Not One Claim Type. It Is Two.
Many private passenger policies in the United States are built from the Insurance Services Office Personal Auto Policy form, though carrier forms vary and yours may read differently. Its physical damage part — Part D, Coverage for Damage to Your Auto — opens with a sentence that does most of the work: the insurer will pay for direct and accidental loss to a covered auto, minus any applicable deductible shown in the declarations.[1] Two words in that sentence decide most scratch questions before coverage is even selected. Direct means the loss is the damage itself, not a consequence of it. Accidental means something happened to the car rather than something happening in the car over four years.
From there the form splits the loss down one of two paths, and the path is chosen by the event, not by the appearance of the damage. The form defines collision as the upset of the covered auto or its impact with another vehicle or object. Everything else on a short, closed list — missiles or falling objects, fire, theft or larceny, explosion or earthquake, windstorm, hail, water or flood, malicious mischief or vandalism, riot or civil commotion, contact with bird or animal, and breakage of glass — is loss considered other than collision.[1] The National Association of Insurance Commissioners describes the same split in consumer terms: collision coverage pays for damage from a collision with another car, an object, a pothole, or flipping over, while comprehensive coverage pays for damage that is not caused by a collision, such as theft, hail, windstorm, flood, fire, or impact by an animal.[2]
Each path is optional, each carries its own deductible, and a policy can have one without the other. That is why the identical-looking white line on a door panel can be a covered claim on one car and an uncovered one on the car parked beside it. The question the adjuster is actually answering is not “how deep is the scratch,” it is “which definition does this event fall under.”
Resist the tempting shortcut of asking who was moving. The form’s collision definition turns on impact with another vehicle or object, not on which party was in motion, so a parked car struck by another vehicle is still generally a collision loss under the parked car owner’s own policy.[1] Work the other direction instead: an impact with a vehicle or object is generally collision under the specimen form unless one of the specifically listed other-than-collision perils fits the facts, or another coverage — uninsured motorist property damage, for instance, where a state permits it — applies. And a scratch inflicted by a person is not automatically an other-than-collision loss; it is one if the facts and the policy wording bring it within a listed peril such as malicious mischief or vandalism. Classify against the exact definitions on your own form rather than against a rule of thumb.
Policy classification
Which Coverage a Scratch Falls Under
| Incident | Coverage That Responds | Why, Under the Form |
|---|---|---|
| A vandal drags a key down the door in a parking lot | Other than collision | Malicious mischief or vandalism is a listed other-than-collision peril in the policy form.[1] |
| You misjudge a turn and scrape a concrete garage pillar | Collision | The form defines collision as the upset of the covered auto or its impact with another vehicle or object.[1] |
| A storm drops a branch on the hood and gouges the clearcoat | Other than collision | Missiles or falling objects and windstorm are both listed other-than-collision perils.[1] |
| A passing truck flings a stone into the door skin | Other than collision | The stone is the moving object. The form lists missiles or falling objects as an other-than-collision loss.[1] |
| You drive over a pipe lying in the roadway and score the bumper | Collision | The car moved into a stationary object, which is impact with an object rather than a falling missile.[1] |
| A deer sideswipes the front fascia and strips paint | Other than collision | Contact with a bird or animal is a listed other-than-collision peril.[1] |
| Swirl marks accumulate from two years of automatic car washes | Not covered | Damage due and confined to wear and tear is an express exclusion under the damage-to-your-auto part.[1] |
The Scratches the Policy Will Not Pay For
Healthy paint fails slowly and invisibly. Ultraviolet light breaks down the clearcoat resin from the top, automatic car wash brushes lay down a haze of fine swirls, road grit sandblasts the leading edges, and after a few years the finish is measurably duller than the day it left the factory. Nothing about that sequence is sudden, and the form says so: the damage-to-your-auto part excludes damage due and confined to wear and tear, freezing, mechanical or electrical breakdown or failure, and road damage to tires.[1]
Read the phrase “due and confined to” carefully, because it is doing narrower work than people assume. It excludes the deterioration itself. It does not convert an accidental impact into an excluded loss merely because the panel was already weathered. A ten-year-old door with faded clearcoat that a vandal then keys has suffered two different things: one excluded, one a listed peril.
The second bar is intent. The policy insures accidental loss, and the liability part separately excludes an insured who intentionally causes property damage.[1] A stranger’s deliberate act is the covered peril of malicious mischief. The policyholder’s own deliberate act is the thing the contract is built to exclude. These are not in tension; they are the same rule read from opposite ends.
Our companion report on whether car insurance covers wear and tear works through the same exclusion for mechanical parts, where the line between gradual failure and sudden loss is drawn in almost identical language.
Covered Is Not the Same as Worth Claiming
The deductible is subtracted before the insurer pays anything, so the covered loss and the payable loss are two different numbers. Run the arithmetic on a real scenario: a keyed rear door produces an $800 refinish estimate, the policy carries a $500 other-than-collision deductible, and the payment is $300. The claim is valid, the peril is listed, the adjuster agrees — and the check covers slightly more than a third of the invoice.
Regulators tell consumers to do exactly that subtraction first. The Texas Department of Insurance advises finding out the deductible before filing, getting repair estimates, and deciding that a claim may not be worth filing if the cost of repairs is about the same as or less than the deductible.[3]
The second number is the renewal. The same Texas guidance states plainly that home and auto premiums can go up for filing most types of claims and that claim-free discounts can be lost — while also drawing a line that matters here: in Texas, companies cannot charge more for claims you filed that the company did not pay, including claims denied because the policy does not cover the damage, or for calling to ask questions about the policy or the claims process.[3] That is a state-specific protection, not a national rule. Ask your own carrier, in your own state, what a paid cosmetic claim does to your renewal before you file one. What a paid claim leaves on your record, and which other insurers can pull it, is covered in our research on who can see your car insurance claims.
The Working Order
Get the written estimate first, then look at the deductible, then ask about rating. Filing to find out what the repair costs inverts the sequence and puts a claim on the record before you know whether it will pay anything.
If someone else caused the scratch, the deductible is not necessarily gone. When the insurer pursues the at-fault party, the NAIC’s model claims-settlement act directs that insurers shall, on the claimant’s request, include the first-party claimant’s deductible in subrogation demands, that recoveries be shared on a proportionate basis with the claimant unless the deductible has otherwise been recovered, and that no deduction for expenses be made from the deductible recovery unless an outside attorney is retained to collect it.[4] It is a model act, adopted in varying forms by states rather than binding everywhere, but it is the template most state claim-handling rules are cut from. Ask, in writing, for the deductible to be included in the demand.
If the scratch came from a hit-and-run in a parking lot rather than a vandal, the path differs again; our research on insurance coverage for a hit-and-run on a parked car covers how those claims are routed, and whether a not-at-fault claim raises your premium addresses the renewal question for damage you did not cause.
Why a Four-Inch Scratch Is Not a Four-Inch Repair
Factory paint is a stack, not a coat. An electrodeposited anti-corrosion primer goes onto bare metal first, a primer-surfacer levels it, the basecoat carries the color and any metallic flake, and a clearcoat seals the whole thing and takes the ultraviolet punishment on behalf of the layers beneath. Where a scuff stops inside the clearcoat, a shop can level it with ultra-fine abrasive and compound, and the stack is never broken.
Where the scratch cuts through the clearcoat into color, primer, or metal, polishing cannot help, because there is nothing left to level — the protective layer is gone at that line and the layers underneath are exposed. American Honda’s published repair sequence for damaged paint shows what replacing the stack actually involves: remove the paint from the repair area and sand with P240 or P320 paper to a feathered edge, apply epoxy primer to any bare metal, apply 2K primer as necessary to level the repaired area, block sand and feather the primer edge to create a level and even surface, then apply basecoat followed by 2K clearcoat with a minimum 2-mil dry film build.[5] Six operations, three chemistries, and a measured film thickness — for a line you could cover with a fingertip.
Then comes the part that surprises policyholders and generates most of the argument on the estimate: where the clearcoat stops is a warranty decision, not a free choice. BASF, in a 2014 response to the Society of Collision Repair Specialists, stated that it recommends applying the specified amount of clear to the entire panel on basecoat/clearcoat repairs, and that this is what makes the repair eligible for the Glasurit or R-M lifetime warranty. Blending the clearcoat, BASF wrote, requires that the thickness of clear be reduced in the blend area, which can result in the blend edge becoming visible after a period of exposure to sunlight and weather — and for that reason BASF will not warrant blended clearcoat edges. BASF is explicit that it has nonetheless developed processes and products for blending clearcoat, intended as a cost-saving measure where an economical, non-warranty repair is required.[10] That is a paint manufacturer’s warranty position for its own systems, not a legal requirement, and other paint systems and OEM procedures set their own terms.
Follow the causal chain to the invoice. Where a repair is meant to carry the refinish warranty, the clearcoat runs to a natural breaking point or panel edge.[11] A breaking point is a physical edge, not a taped line — the gap where the door ends, a seam under a molding. To reach one cleanly, trim, lamps, glass, and weatherstripping in the path have to come off and go back on, and that removal and installation is billable labor the estimating databases treat as a separate operation rather than part of the refinish time.[11] The scratch is four inches. The refinish envelope is the whole panel plus whatever has to be disassembled to reach its edges.
When the Scratched Panel Is Also a Radar Window
On a modern car the painted plastic at the corners of the bumper is not only trim. Blind-spot radar units sit directly behind it, and the cover they work through is therefore part of the sensing system rather than a decorative skin over it. That is why manufacturers treat refinishing it as a technical operation with published limits: Honda and Acura state that the composition of the repair materials and the increased material thickness in a repaired area may interfere with radar unit operation.[9] The controlling constraint is what the manufacturer publishes for that vehicle, not a general rule about paint.
That is why several manufacturers have taken the repair option off the table entirely in the radar zone. Rivian’s position statement for the R1T and R1S states that in addition to repairs, repainting with primers, sealers, and base coats is not allowed in the No-Repair Zone; only clearcoat can be applied there; and if any repair beyond clearcoat application is required in the radar transmission area, the bumper must be replaced.[8] Honda and Acura instruct that no bumper repairs be made in the areas over or near the two radar units on vehicles with the Blind Spot Information system, because the composition of the repair materials and the increased material thickness in the repaired area may interfere with radar unit operation.[9]
Where refinishing is permitted, it is permitted inside a measured tolerance rather than at a painter’s discretion. Honda and Acura limit paint film thickness to a maximum of 300 microns with 200 preferred, and American Honda’s AcuraWatch 360 position statement recommends that basecoat thickness on bumper covers not exceed 40 microns.[9] Those are engineering budgets, and factory film already spends part of them. A cover that has been refinished once may have no room left for a second pass.
OEM radar-zone limits
What Two Manufacturers Allow Over a Bumper Radar
| Manufacturer Position | Published Restriction | Effect on a Scratch Claim |
|---|---|---|
| Rivian R1T and R1S[8] | Repainting with primers, sealers, and base coats is not allowed in the radar No-Repair Zone. Only clearcoat may be applied there. | Any repair beyond clearcoat application inside the radar transmission area means the bumper is replaced, not refinished. |
| Honda and Acura, Blind Spot Information system[9] | No bumper repairs over or near the two radar units. The composition of the repair materials and the increased material thickness may interfere with radar unit operation. | A scratch that sits over a blind-spot radar converts a refinish line into a bumper replacement line on the estimate. |
| Honda and Acura, total paint film[9] | Paint film thickness should be limited to a maximum of 300 microns, with 200 microns preferred. | Factory film plus a repair film has to stay inside that envelope, so a panel already refinished once may have no budget left. |
| Acura, AcuraWatch 360 position statement[9] | American Honda recommends that basecoat paint thickness on bumper covers not exceed 40 microns. | The color layer carries its own separate ceiling on radar-equipped covers, independent of the total film limit. |
The practical consequence runs straight back to the claim decision. If the scratch sits over a radar zone on a vehicle whose maker forbids repair there, the line item is no longer “refinish bumper cover.” It is a new cover, its color, and whatever calibration the manufacturer requires afterward — which is how a blemish you could cover with a business card crosses the deductible threshold without any argument at all.
Why a Compliant Paint Job Needs a Booth, Not a Driveway
The other reason a scratch costs what it costs is federal air rules, and they are the part of the invoice that never appears as a line item. Automotive primers and color coats can contain compounds of chromium, lead, manganese, nickel, or cadmium, which the Environmental Protection Agency designates collectively as the target hazardous air pollutants for this industry. When a gun atomizes coating, the fraction that misses the panel becomes airborne overspray carrying those compounds.[6]
The rule that captures it is 40 CFR Part 63 Subpart HHHHHH, known throughout the collision trade as the 6H rule. It is a rule about commercial operations, and it says so: under § 63.11169(d)(3), the subpart does not apply to surface coating performed by individuals on their personal vehicles, possessions, or property, either as a hobby or for maintenance of those personal vehicles, and it also does not apply when those operations are performed by individuals for others without compensation.[6] Repainting your own fender in your own garage is not what this regulation is aimed at.
The same paragraph draws the line at which an individual stops being a hobbyist. An individual who spray applies surface coating to more than two motor vehicles or pieces of mobile equipment per year is subject to the subpart’s motor vehicle coating requirements regardless of whether compensation is received.[6] The EPA publishes its own plain-language summary of the same rule for body shops.[7] Federal air rules are also not the only rules in play: state and local air districts set their own coating-content limits and can separately restrict outdoor spray painting, so check the requirements where the work would be done.
For the covered operations — which is to say, every body shop that could hand you a written estimate — what follows is capital equipment, and the shop’s hourly rate is where it gets recovered.
Federal refinishing rule
What 40 CFR Part 63 Subpart HHHHHH Requires
| Requirement | What the Regulation Says |
|---|---|
| Who is covered, and who is not | Coating performed by individuals on their own personal vehicles as a hobby or for personal maintenance is excluded, as is uncompensated work done for others; but an individual who spray applies surface coating to more than two motor vehicles or pieces of mobile equipment per year is subject to the subpart, whether or not compensation is received. |
| Spray equipment | High-volume, low-pressure equipment is defined as a spray gun designed and operated between 0.1 and 10 pounds per square inch gauge air atomizing pressure, measured dynamically at the center of the air cap and at the air horns. |
| Enclosure | Booths and preparation stations used to refinish complete vehicles must be fully enclosed with a full roof and four complete walls or side curtains, ventilated at negative pressure; a sealed booth with an automatic pressure balancing system may run up to 0.05 inches water gauge positive. |
| Filtration | Booths, preparation stations, and mobile enclosures must be fitted with filter technology demonstrated to capture at least 98 percent of paint overspray, using a procedure consistent with ANSI/ASHRAE Standard 52.2-2017. |
| Gun cleaning | Spray gun cleaning must be done so that an atomized mist or spray of cleaning solvent and paint residue is not created outside a container that collects the used solvent. |
| Painter certification | All painters must be certified as trained in proper spray application and equipment setup; the certification is valid for no more than five years, after which refresher training and re-certification are required. |
Read the table as an economic statement rather than a compliance checklist. A negative-pressure booth with a full roof and four walls, 98-percent-capture filters that get consumed and replaced, an enclosed gun washer, and a painter whose certification expires on a five-year clock are fixed costs that exist before a single scratch is repaired. They are the reason a professional refinish starts in the hundreds of dollars, and the reason a $150 offer to spray a panel outdoors is not really a competing quote — it is a different operation, done without the equipment, filtration, and certification the covered shops are carrying.
The Loss That Can Survive a Perfect Repair
Suppose everything goes right. The clearcoat runs to the breakpoint, the film thickness lands inside the OEM envelope, the color matches under sodium light and daylight both. The car is physically restored. Whether it is also worth what it was is a separate and much softer question. A repair or a claim may be reported to a commercial vehicle history database, and a buyer who sees it there maydiscount the car — that potential gap between pre-loss market value and post-repair market value is inherent diminished value.
Treat it as contingent rather than automatic. Whether any loss exists at all, and how large it is, depends on whether the event was reported, the severity of the damage, the quality of the repair, what comparable sales actually show, and the law of the state. The NAIC’s own review describes the assessment process as subjective, notes that appraisal formulas and private appraisers produce different figures, and observes that the loss is generally not realized until the vehicle is sold or traded.[12] A cosmetic scratch that never produced a reported claim may carry no measurable diminished value at all.
Whether anyone owes you for it depends on which side of the claim you are on. The policy’s limit of liability provision gives the insurer the lesser of the actual cash value of the damaged property or the amount necessary to repair or replace the property with other property of like kind and quality.[1] Insurers read “repair” as restoring the physical thing, and most courts have agreed with them on first-party claims. The NAIC’s Journal of Insurance Regulation surveys the case law: the Texas Supreme Court in American Manufacturers Mutual Insurance Company v. Schaefer(2003) held the insurer’s obligation limited to what the limit of liability provision specifies; the Florida courts in Siegle v. Progressive (2002) found the contract clear and the diminished value loss not owed; and the California Court of Appeal in Ray v. Farmers Insurance Exchange (1988) declined to rewrite an otherwise unambiguous limitation of collision coverage to provide for a risk not bargained for.[12]
Georgia is the documented exception. The NAIC review reports that Georgia is the only state with a clear legal direction that first-party auto claimants are entitled to recover diminished value losses from their own insurer, following the Georgia Supreme Court’s 2001 decision in State Farm Mutual Automobile Insurance Co. v. Mabry, which held that the first-party obligation included not just payment for repairs but also the diminished value loss, and which turned on the vehicle’s worth rather than its condition. Georgia has historically calculated the figure with the 17(c) formula — ten percent of NADA retail value, multiplied by a damage modifier and a mileage modifier each ranging from zero to one — a formula the NAIC review itself criticizes, partly because mileage is already embedded in the retail value and is therefore counted twice.[12]
Third-party claims are a different body of law and a friendlier one. Where another driver caused the damage, the claim sounds in tort rather than contract, and the NAIC review reports that many states allow recovery for diminished value in a third-party claim. As a practical matter, it notes, the settled diminished value loss tends to run about 10 to 20 percent of the direct physical damage loss, so a $10,000 repair would likely produce a claim between $1,000 and $2,000 — small enough that attorney involvement is rare and small claims court is often the venue.[12] For a cosmetic scratch, scale those percentages down accordingly: on a $1,200 refinish, the diminished value component is not usually the reason to file.
If the disagreement is about the value the adjuster assigned rather than about coverage, our research on how insurance adjusters determine the value of a car explains the valuation inputs that produce the number on the settlement sheet.
The Order of Operations
- Name the event, not the damage.Write down what happened, then read it against your own policy’s definitions. An impact with another vehicle or object is generally collision under the specimen form — regardless of which party was moving — unless a specifically listed other-than-collision peril such as vandalism, a falling object, or contact with an animal fits the facts, or another coverage applies.[1]
- Check that you bought that coverage. Collision and other-than-collision are separate optional coverages with separate deductibles on the declarations page. A liability-only policy answers neither.[2]
- Get the written estimate before you call. Ask the shop to state the refinish breakpoint and to list the removal-and-installation operations needed to reach it, so the number reflects the actual repair envelope rather than the length of the scratch.[11]
- Ask whether a sensor sits behind the panel.If the scratch is on a bumper corner, have the shop check the manufacturer’s position statement and body repair manual for a no-repair zone and film-thickness limits before anyone quotes a refinish.[8] [9]
- Subtract the deductible, then ask about rating. If the repair is near or below the deductible, there is nothing to collect; if it is well above, ask the carrier how a paid claim of that type is treated at your renewal.[3]
- If someone else did it, ask for your deductible in the demand. The NAIC model act directs insurers to include the first-party claimant’s deductible in subrogation demands on request and to share recoveries proportionately.[4]
- Keep the paperwork either way. The estimate, photographs, the repair invoice, and the film-thickness and calibration documentation are what support a later diminished value claim against an at-fault driver.[12]
Frequently Asked Questions
Is a keyed car a comprehensive claim or a collision claim?
Other than collision, sold in most markets as comprehensive. Malicious mischief or vandalism is one of the perils the ISO Personal Auto Policy lists as loss considered other than collision, alongside fire, theft or larceny, windstorm, hail, water or flood, riot or civil commotion, and contact with bird or animal.
I scraped a pole in a parking garage. Which coverage is that?
Collision. The form defines collision as the upset of the covered auto or its impact with another vehicle or object, so a scrape against a fixed structure is an impact with an object and is paid, if at all, under collision coverage subject to that deductible.
My paint is scuffed and dull from years of car washes. Will insurance pay?
No. The damage-to-your-auto part excludes damage due and confined to wear and tear. Gradual clearcoat degradation, swirl marks, and general weathering are maintenance conditions rather than sudden accidental losses, and no coverage grant reaches them.
The estimate is $800 and my deductible is $500. Should I file?
That is a $300 payment against a claim on your record. The Texas Department of Insurance advises finding out your deductible and getting repair estimates before filing, and says that if the cost of repairs is about the same as or less than the deductible you may decide the claim is not worth filing. Ask your own carrier how a paid claim of that size affects your renewal.
Why does the shop want to repaint the whole door for a small scratch?
Because where the clearcoat stops decides whether the repair carries a refinish warranty. BASF told the Society of Collision Repair Specialists that it recommends applying the specified amount of clear to the entire panel to qualify for the Glasurit or R-M lifetime warranty, and that it will not warrant blended clearcoat edges because the reduced film can become visible after sunlight and weather exposure. BASF also states it has developed blending processes intended for economical, non-warranty repairs, so this is a manufacturer warranty position rather than a legal rule, and other paint systems and OEM procedures differ.
How thick should the repaired clearcoat be?
American Honda Service Bulletin 20-047 specifies a minimum 2-mil dry film build of 2K clearcoat over the basecoat, after sanding to a feathered edge with P240 or P320 paper, applying epoxy primer to bare metal, and leveling with 2K primer. That is one manufacturer’s published figure for its own repair; other makers publish their own.
My scratched bumper has blind-spot radar behind it. Can it be repainted?
Check the position statement before anyone quotes. Rivian states that repainting with primers, sealers, and base coats is not allowed in the No-Repair Zone on the R1T and R1S and that the bumper must be replaced if any repair beyond clearcoat is required in the radar transmission area. Honda and Acura instruct that no bumper repairs be made over or near the two Blind Spot Information radar units because material composition and thickness may interfere with radar operation.
Can I just have someone spray the panel cheaply outside a shop?
Federal law treats personal and commercial work differently. Under 40 CFR § 63.11169(d)(3), Subpart HHHHHH does not apply to coating individuals perform on their own personal vehicles as a hobby or for personal maintenance, nor to uncompensated work for others — but an individual who spray applies surface coating to more than two motor vehicles or pieces of mobile equipment per year is subject to the rule regardless of compensation. For covered operations, spray-applied coatings must be applied in a booth, preparation station, or mobile enclosure fitted with filters demonstrated to capture at least 98 percent of paint overspray. State and local air rules may impose further restrictions, including on outdoor painting, so check the requirements where the work would be done.
My car was repaired perfectly but is now worth less. Can I recover that?
On a first-party claim against your own insurer, generally no. The NAIC Journal of Insurance Regulation reports that Georgia is the only state with a clear legal direction entitling first-party claimants to diminished value, following State Farm Mutual Automobile Insurance Co. v. Mabry (2001), and that courts in Texas, Florida, and California have read the limit of liability provision as owing only repair or actual cash value. Many states do allow recovery on a third-party claim against the driver who caused the damage.
Someone else scratched my car. Do I get my deductible back?
Possibly, through subrogation. The NAIC model claims-settlement act directs that insurers include the first-party claimant’s deductible in subrogation demands upon request, share recoveries proportionately unless the deductible has otherwise been recovered, and make no deduction for expenses from the deductible recovery unless an outside attorney is retained to collect it. States adopt the model in varying forms, so ask your carrier in writing.
