My car was sitting outside in a parking lot and had dirt on the rear bumper and someone made a design with the fingers in it and basically scratched the paint with there design. I don't know why people would do that kind of stuff
Sorry to hear this man, people should not even be touching your car. If it's not their property they need to keep their hands off. People just have no respect for others or others property. When I get my Corvette if I caught someone touching my car without my permission I'd probably kick the snot out of them. I've had one car keyed over the years, so I always expect the worst when I come out and see someone near my car. You can probably take some polishing compound and buff it out.
