How to fix a scratch on your GMC
A stone chip or scratch on your GMC does not need a body shop. Matched to your exact factory paint code and applied at home, you can make it disappear in under an hour — and stop it rusting. Here is exactly how.
- 1
Assess the damage
Run a fingernail across the mark. If it catches, it has gone through the clear coat into the colour — that is what touch-up paint fixes. If it does not catch, a polish may be enough. Deep gouges that reach bare metal on your GMC should be primed first so they do not rust.

Find your exact paint code
Guessing the colour never matches. Every GMC has a factory paint code on a sticker (usually in the door jamb, under the bonnet or in the boot). Read it, and match your touch-up kit to that exact code — not by eye.

Clean and prep
Wash the area, then wipe it with the prep solution and let it dry fully. Paint will not bond to wax, grease or moisture. Mask around the scratch if it is on a body line.

Apply in thin layers
With the micro-brush, lay the colour-matched paint into the scratch in thin coats — build up gradually, do not flood it. Let each coat dry before the next.

Level and finish
While wet, glide the application card flat to lift the excess so paint stays packed in the scratch. Once dry, run the corrector over it and finish with the clear coat for a glossy, factory-matched result.

Common questions
Does touch-up paint actually work on a GMC?
Yes — for stone chips and scratches that have gone through the clear coat into the colour. Matched to your exact factory paint code and applied in thin layers, the repair blends in and protects the metal underneath. It is not for deep dents or large panels — those need a body shop.
Will the colour really match my GMC?
It matches when it is mixed to your exact factory paint code, not guessed by eye. That is why finding your code first matters. Our kits are matched to the code — colour-match guaranteed, or 30-day money back.
How long does the repair take?
Most chip and scratch repairs take 20–40 minutes of hands-on work, plus drying time between coats. No booking, no waiting for a body shop.
What happens if I leave a scratch unrepaired?
A scratch that reaches bare metal will start to rust, and rust spreads under the paint around it — turning a cheap touch-up into an expensive panel repair. Sealing it early is the whole point.
