I just bought a 1990 5.0 Coupe about 2 months ago and had a question about the molding. There are some scuffs and various places on the black moldings that wrap around the car. Does anyone know if there is a way to sand these moldings? I'm going to get it painted soon and will be painting them white as well. I'm afraid if I don't do something it will show in the paint... If anyone has any suggestions let me know? These pieces are expensive new...
