I ended up paying a guy who has a mobile dent removal service. He came out first and gave me an estimate and it sounded reasonable. His name is TIP with "Perfect Touch" in Monterey, CA.
Well, I'm sort of amazed.. almost every dent has been removed and 90% of them would be impossible to find now. I don't know how he did it but it's almost like magic. The car looks so much better it's amazing and it wasn't terribly expensive.
His technique was to go in from the back side and push the dent back out. He had to remove tail lights, door panels, wheel well panels, etc. to do it, but he's been doing it for 20 years and know just how to get at them.
