Someone keyed my dads explorer, so he painted the WHOLE door with off the shelf auto touch up spray. Now, 2 years later, the door looks terrible. Flaking, and just plain bad. I want to remove he touch up paint and get back to the original paint, and just do a normal touch up on the scratch. Is there a way to get this stuff off, without damaging the original paint underneath ? The only thing i could think of is buff real hard with some compound and a machine buffer. Anyone have any other suggestions ?
