I'm re-posting this from a NASA board cuz it's cool and very GRM. No relation, full credit, etc.
I have been asked to post a method of dent removal that I came up with. I had a dent in the rear quarter panel below the running light. I took a basket ball, deflated it, jammed it in the well and inflated it. The dent popped out and looked almost perfect. I have passed this idea on to several of the SoCal racers and all who have tried it have had positive results. Tim used a soccer ball which he said worked fine. He did his rear quarter panel and door. He backed the ball up on the door with 2x4s.
Last weekend at Autoclub Speedway I was driving a loaned car which was wacked around a bit. I jammed the basket ball in the speaker hole behind the door, inflated it and the dent was gone.
