If you've got a few dings on your car, contact Chris Jacob at
http://www.diablodents.com. He's located in Pleasanton, but travels throughout the San Francisco Bay Area.
Picked up three dings in a two week period, got two dings on the passenger side door and a nasty one on the driver's side quarter panel (in garage from the wife!) and, as usual, he fixed them with zero trace they were ever there.
FYI.
