my grilles got scratched easily especially the back doors you think if I sandblasted them it would help keep the paint on them?
Definitely will help to blast em, you should take em somewhere unless you have a pretty powerful compressor to do it. Blasting requires some good compressor strength.
Paint doesn't stick well to old paint. Plus, if you use almost any adhesion promoter on old paint, the promoter can eat into the old paint depending on what type it is. It will definitely eat SEM Surecoat like it was water to sugar.
back doors look sexy!
Thanks
