OUCH! That did leave a mark! At least you're honest enough to fess up and admit fault. A few years ago, my neighbor asked if I could repair the quarter panel on his black SUV damaged from a hit and run in a parking lot. After a quick look, it was obvious that the "hit and run" was done by a masonry wall with white paint.
My bumper is back and almost "normal" or repaired...not perfect but certainly better than it was. Only cost me a '64 grill...
