...would it cost to fix it? I had just bumped the rear bumper of my bmw x5 on another car and it had created a SMALL scratch (about the size of a coaster.) one the right side of my rear bumper. There are absolutely no dents or anything, just a scratch that actually somewhat dissapeared when i rubbed it, but its still there. How much would it cost to fix it and how would they fix it? would the just paint over the scratch or would they need to paint the entire rear bumper?
