While parked at a Tesla Supercharger which is located in a parking garage, my car rolled slowly into the charging stand. Caused 2 small dings in the rear bumper. Evidently, paintless ding removal is not possible since the bumper is made out of plastic! Only metal parts are able to be treated with paintless dent removal. I asked a couple of local body shops about the possible repairs; apparently they will have to repair and repaint the entire rear bumper. I have no idea how much it's going to cost to repair. Anyone experience a similar rear bumper issue?
