My rear bumper made contact with a fender of another car. It was basically a bump; no damage to the bumper, slight damage to the fender. As stated, there was no damage such as dent to the bumper, but it did leave a scuffed looking area on the bumper. The bumper is black so the scuff is not real noticeable, except to me. I attempted to remove the marks with Pinnacle Paintwork Cleansing Lotion, but that failed. Before trying something else, I decided to get advice from some people that have more experience in this type of removal than I have. Obviously, I can take it to the dealer's body shop and I am sure they can take care of it, but I thought I would see what I can do first. Your advice would be appreciated.
