Default Any tips on how to touch up the marks left behind from rim weights??

Mine has the polished aluminum wheels and the 12 year old tires came off yesterday. The rim weights left some marks in the clearcoat? Any tips on how to clean them up???





Thanks!

Only thing you can do is Buff that out but it will take the clearcoat off with it.

You'll probably never be able to get that completely out. I have that too. That is surface pitting in the aluminum caused by the weights. Aluminum usually will pit and corrode when in direct contact with another dissimilar metal. It's galvanic corrosion.

What amazes me is why GM would put ugly exterior clipon balancing weights on aluminum rims? Probably to save a buck or two. They did that to all their cars. It was the same situation when I owned my '97 Grand Prix.
