It seems that no one is really worried about marks or bare spots where the ground wire/clamp is, as long as it is discreet. I am PARANOID about rust, which is why I like PC. If you saw my project car you’d understand why.
So is anyone worried about rust creep? Any tips on how to fill in these spots? I know the trick about threading a bolt and using that to ground, but what about when that is not possible? Thanks in advance!
