I have given up on fixing things like that on my vehicles. If it happened once, it's going to happen again. This really rings true if you or your wife park in a crowded parking lot for work. My wife works downtown and parks in a covered garage. Dings, scratches, gouges, dents show up every god damn week. We just waited till somebody really donked the side and had it all redone at once using our insurance. Sucks, people are assholes in parking lots.
