I also had a good experience with a knowledgeable and skilled paintless dent repair shop. My wife's Cadillac, 1995 DeVille, suffered hail damage on nearly every panel. Reynolds collision center in Oklahoma City repaired it. This was about 6-7 years ago. I sold the car earlier this year and I was never able to find any evidence that there had been hail damage after they finished. It wasn't cheap, $750 as I recall, but the quality repair was excellent.
