My car was re-painted a few months back, and the body shop has since gone out of business. an appraiser recently looked at my car and pointed out the "overspray" - how can I remove that? my car is a 2002 Cabrio, and the paint was done on the bottom of the INSIDE of the passenger door, where a bolt rusted. some paint got on the bottom of the outside of the car, behind the front passenger fender. the bottom of my car is painted black from the factory, but the body is silver. you can see some silver paint on the black part. any way to wipe or clean off the silver paint from the black part?
