My car has what looks like some white paint transfer on the front right black trim. I tried covering it up with Poorboys Trim Restorer with no luck. Then I tried Back to Black and didn't work. Finally I busted out a magic eraser and still no luck.
You could try WD-40 as well. Use it on a soft towel, then scrub if necessary. I suppose you could try letting it sit for a little while if that isn't enough. I always figure if I can solve the problem with stuff lying around the house it's better than going out and buying something, or waiting for shipping. ..But no one can deny that they love new products right?
