Hey guys, I got myself into a little bit of a situation. I noticed I had these light spots in the ABS plastic insert that is part of the rear bumper. I tried getting them out with some concentrated dish soap and a rough sponge but it didn't really do anything. Then I thought maybe a little Goof Off could get rid of them. It did, along with some of the paint apparently? I thought the plastic was black through and through so I didn't think the Goof Off would strip anything off of it. Nevertheless, I now have white streaks (see below). I tried using some Mothers Back to Black that I had laying around but that didn't help at all. Any suggestions how to repair this now?
