Most car scratches can be DIY-repaired for $15-$50 in materials vs $200-$650 shop repair — 85-95% savings for 30-90 minutes of work.
The right kit depends on scratch depth. Clear-coat scratches (fingernail doesn’t catch) polish out with $15-$30 in materials. Scratches through paint to primer or metal need full color+clear repair for $30-$50. This guide covers all four scratch depths and the exact kit for each.
- You have a scratch you can identify by depth
- You have time for 30-90 minutes + optional 24-48 hour cure
- You want to save $200-$500 per scratch
- The scratch is under 6 inches long
- You’re comfortable with basic detailing tools
- The scratch is over 12 inches (full panel work)
- Multiple deep scratches in same area (panel refinish)
- You have very metallic or tri-coat paint (professional matching)
- You don’t have shade or garage to work in
- Scratch extends through structural panel
The 4 scratch depths and how to test
Test with your fingernail
Drag your fingernail across the scratch:
- Fingernail doesn’t catch: Clear coat only. Polish repair.
- Fingernail catches lightly: Through clear into base color. Touch-up paint + polish.
- Fingernail catches strongly: Through base to primer. Prime + paint + clear.
- You see bare metal (silver/white): Full paint system + immediate rust risk.
Second test — light angle
Shine a flashlight at 45° across scratch:
- Uniform reflection = clear coat only
- Different color visible = through base coat
- White or silver visible = through primer to metal

How do I know how deep my scratch is?
Fingernail test: doesn’t catch = clear coat only. Catches lightly = base coat. Catches deeply = primer/metal.
Can I fix any scratch DIY?
Under 12 inches: yes. Deeper structural damage: no. Multi-panel damage: no.
How long does DIY scratch repair last?
5-15+ years if done right. Shorter if prep skipped.
What if my paint is metallic?
Very small scratches yes. Larger areas — professional matching required for metallic/tri-coat colors.
Can I fix rock chips too?
Yes — use touch-up paint kit. Same technique as scratch depth 2-3.
How much can I save vs shop?
$200-$500 per scratch vs shop repair. $650+ for professional panel refinish.
Do I need clear coat?
For depth 2-4 yes. For depth 1 (clear coat only), no.
Should I try to fix or accept it?
Depth 1-2: fix — easy and cheap. Depth 3-4: fix soon to prevent rust. Rust already starting: fix immediately.
Bottom line
Match your project to your skill level and available time. DIY saves substantial money vs shop repair when done correctly. Always err toward more prep + safer approach vs speed.
