Hey all! New member. When I took delivery of my car a few months back, I removed the front license plate bracket, waxed the bumper underneath it (Meguiar's #26) , and reinstalled the bracket. When I removed the bracket today, there is this dark discoloration where the bracket made contact with the bumper all this time. It is smooth to the touch. I used polishing compound, and then rubbing compound, to no avail. Is there anything I can do about this? I've included photos.
