Somebody was kind enough to use my wife's Audi wagon for bumper car practice last weekend while it was parked on the street. They pushed in the rear wheel arch a bit, scuffed the paint between the wheel and bumper, and whacked the mirror. New mirror glass on order($87), but I'm curious about PDR on the wheel arch. Anybody have this done, or even better, DIY'd this? Is it possible? I realize a picture would be nice, but I did not get a chance yet.
