Hard to tell in the pic but there are several scratches on my carbon fibre exhaust can. It's hard to tell but i dont think they have reached the carbon just scratched the resin. Only one is fairly deep that may have reached the carbon. Can these be fixed by cutting? ie with a usual car polish type. Can i use wet/dry paper and what compound if any? Anyone had much experience with buffing carbon fibre? They arn't that noticable but just annoying cause i know they are there... any help muchly appreciated.
