Thanks guys. Long way to go though, I need to build an engine and gearbox..... and everything else!
2K primer on the stone chip. This is just normal 2K not acid etch. Acid etch is best used on bare metal as the acid etches into the steel to provide better adhesion. Acid on a plastic based surface is not recommended.
Followed by a wet coat of 2K solid (not metallic) There's quite a composite of layers under here now which should offer some serious protection. This was then flatted to get rid of any high spots and leave an even finish. Ive seen cars painted over stone chip and the results can look a bit of a mess. Hopefully this method will provide the optimum base for the metallic paint and clear coat
You can't keep lashing paint on otherwise it will craze, I need to leave this for a good few days to allow the solvents to evaporate.
