I have some pinstripes on the car ,and one side was peeling.Decided to remove and replace.When I took off the drivers side they pretty much fell off,leaving little residue.I like the look of the car w/o the pinstripes so I decided to remove the other side.They came off....1 inch at a time!!Left behind a lot of residue.Anyone have a suggestion how to get the residue off without damaging the paint?
