Removing tar/rubber is probably the best use for WD-40. It ***** as a penetrating fluid. However, I wouldn't use it on my finish either. There are several solvents at the parts store. They all work well just ask one of the clerks. I have a small bottle of Mopar Tar Remover that I got from VOI 6 and I think it's the best stuff I've used.
