Fixing a scratch or dent is usually worth it when the damage goes through the paint to primer or bare metal, when you plan to sell, trade in or return a leased car soon, or when it sits on a panel that rusts. A scratch your fingernail doesn't catch is often only in the clear coat and may polish out. Light cosmetic marks on an older car you plan to keep can often be left alone.
Run your fingernail across the scratch. That ten-second test answers half the question of whether fixing a scratch or dent is worth your money. The other half depends on your car, your plans for it, and what is under the paint.
How deep is your scratch? Use the fingernail test
Factory paint is built in layers. From the top down:
- Clear coat: a transparent layer that gives the shine and protects the color
- Base coat: the color itself
- Primer: usually gray or white, bonding the paint to the panel
- The panel: steel, aluminum or plastic
Drag a fingernail lightly across the scratch. If it glides over without catching, the scratch is probably only in the clear coat. Many of those can be compounded and polished until they disappear or nearly do.
If your nail catches, the scratch has likely reached the base coat. Polishing won't remove it. It will need touch-up at minimum, and often a refinish of the panel for a clean result.
If you can see gray, white or shiny metal in the groove, you are through to primer or bare metal. That is the one to take seriously.
Why scratches through the paint can lead to rust
Paint is what keeps moisture off steel. Once a scratch or a cracked dent exposes bare steel, water and road grime reach the metal and rust can start. Surface rust in a scratch spreads under the surrounding paint, which lifts and bubbles. By the time you see bubbles, the repair area has grown.
Plastic bumper covers don't rust, which makes a scratch there a cosmetic question. Aluminum panels don't rust the way steel does, but they can corrode when the paint is broken. Steel doors, fenders, hoods and quarter panels are where a deep scratch should not wait long.
Do dents and scratches hurt resale or a lease return?
When you trade in or sell, dealers and buyers look at body damage and price the repair into their offer. Their number for fixing it is rarely in your favor.
Leases work differently. Your lease contract sets what counts as normal wear and what you'll be charged for at turn-in. Pull out that wear guide a couple of months before your lease ends, then get a repair estimate for anything that falls outside it. You can compare the two and decide which costs less.
If you plan to keep the car for years, resale matters less. Rust risk matters more.
Key scratches and door dings: what the fix involves
Key scratches
A keyed car usually has a long scratch that crosses two or more panels, and it almost always goes through the clear coat. Each damaged panel needs refinishing, and adjacent panels may need color blended so the match holds up in sunlight. That makes a key scratch a bigger job than its width suggests. If someone keyed your car on purpose, report it to police and ask your insurance agent whether your policy covers vandalism before you decide how to pay. Our post on whether to file a claim or pay cash for minor damage can help you weigh it.
Door dings
A small ding with the paint intact is a different animal from a dent with cracked paint. Some specialists offer paintless dent repair, a technique that pushes dents out from behind without repainting, and it can work well on shallow dings where the paint hasn't cracked. Once the paint is cracked or the dent sits on a sharp body line, conventional repair usually makes more sense: the dent is pulled, the surface is filled and shaped, then primed and painted. Our dent and scratch repair page explains how we handle those.
When fixing a scratch or dent isn't worth it
Sometimes the smart move is to leave it. That can be the case when:
- the scratch is only in the clear coat and you can live with it, or polish it yourself
- the damage is a scuff on a plastic bumper that won't rust
- the car is older, you plan to drive it until it quits, and the repair would cost a large share of what the car is worth
- the dent is small, the paint is unbroken, and it doesn't bother you
Nova Body Shop will tell you when a repair isn't worth doing. We would rather you spend the money on tires.
What you should not ignore is paint that is cracked, chipped to metal or starting to bubble. Those get more expensive with time. If the damage is on a bumper, our guides on whether to repair or replace a bumper and on what sets bumper repair cost in Austin go into more depth. For paint-only work, see our auto paint page.

Frequently asked questions
Is it worth fixing a scratch or dent on an older car?
Fixing a scratch or dent on an older car is worth it if the damage has exposed bare metal on a steel panel, because rust can spread from there. If the mark is cosmetic, the paint is intact, and you plan to keep driving the car, leaving it alone is often reasonable. Compare the repair estimate to what the car is worth to you.
How can I tell if a scratch is too deep to buff out?
Run a fingernail lightly across it. If your nail doesn't catch, the scratch is probably in the clear coat and may polish out. If your nail catches, or you can see gray primer or metal, the scratch is too deep to buff out and needs touch-up or refinishing.
Will a small scratch on my car rust?
Only if it exposes bare steel. A scratch in the clear coat or color layer won't rust, and plastic bumpers don't rust at all. A scratch down to metal on a steel panel can start rusting, so it should be sealed and painted.
Should I fix dents before I return my leased car?
Check your lease's wear and tear guide first, since it sets what you'll be charged for at turn-in. Then get a repair estimate for any damage outside those limits and compare it to the likely charge. Pick whichever costs you less.
Someone keyed my car. Is it worth fixing?
Usually yes, because key scratches almost always cut through the clear coat and can reach metal. Report it to police, then ask your agent whether your policy covers vandalism and what the deductible is. Get a repair estimate so you can compare it to that deductible.
