that is actually a good idea. However, the handbrake, I don’t think would be able sand it? and the problem is the scratches are also around the key ignition, next to the seatbelt holder and etc. I don’t know, cause spraying it would be difficult because it’s very small and tight areas and small scratches, so it would be tough to not affected other areas. So I’m not sure, if using paint and a paint brush would work, but again, it doesn’t seem like the best idea to use a paint brush ahaha.With as many scratches and marks as your pictures show you should definitely sand, prime and re-spay those parts and probably re-do the whole center console area; either in place or remove the pieces, this way everything will match.
Have you repainted anything in your car?
And how did it turn out?
