Key scratches: assess before you fix
The fingernail test
Drag your fingernail lightly across the scratch, perpendicular to its length:
- Nail glides over: Clear-coat scratch only. DIY fix works. 5-10 minutes with ScratchX.
- Nail catches slightly: Through clear coat, into the base coat. DIY still works but takes more effort. 15-30 minutes with compound + polish.
- Nail catches deeply, primer/metal visible: Through the paint entirely. Need touch-up paint + clear coat + polishing. 30-60 minutes plus curing time.
DIY key scratch repair by depth
Level 1: Clear-coat only (fingernail glides)
- Wash + dry the panel.
- Apply pea-sized ScratchX to foam applicator.
- Work in tight circles for 30-45 seconds.
- Cross-hatch pattern for 15 seconds.
- Wipe clean with microfiber. Repeat if visible.
Level 2: Through clear coat (nail catches slightly)
- Wet-sand scratch lightly with 3000-grit paper + soapy water.
- Apply cutting compound (Meguiar’s M105 or Ultimate Compound) with foam pad on dual-action polisher.
- Work at moderate speed for 60-90 seconds.
- Follow with fine polish for gloss restoration.
- Apply wax or sealant.
Level 3: Through paint (primer/metal visible)
- Wipe scratch with isopropyl alcohol.
- Apply matched touch-up paint into scratch using the pen tip. Fill just below surface.
- Let dry per label (15-30 minutes).
- Repeat if scratch is deep — build up thin layers.
- Once dry, apply clear-coat pen over color.
- Let cure 24-48 hours.
- Wet-sand very lightly with 3000-grit to level, then polish with scratch remover.
When to skip DIY
- Long scratches (over 12 inches)
- Scratches across body character lines
- Multiple scratches on same panel
- Metallic or pearl paint (harder to match)
- Scratches exposing significant primer area (rust risk)
Insurance for keyed cars
- Comprehensive coverage handles vandalism/key scratches
- Deductible typically $250-$1,000

Should I file an insurance claim for a key scratch?
Only if repair cost significantly exceeds your deductible. Comprehensive claims usually don’t raise rates.
Do I need to see a body shop for a key scratch?
Not if the scratch passes the fingernail test (no catch). Deeper scratches or multiple panels — yes.
Will scratch remover permanently fix a key scratch?
For clear-coat scratches yes — permanently. For deeper scratches the wax fill can wash out in 6-18 months. Reapply as needed.
