Just bought a 95 SL320. The paint is in great shape but the "brainiac" that sold the car to me ran it though the car wash and had it waxed. He still had the paint/marker that he used to put the price on the windshield still on the car when he went through the car wash!!! The white paint/marker is under the wax. I tried to use the clay and polish but that would not remove it. What can I use to strip the wax that will not hurt my clear coat or finish.Any ideas or thoughts?
