Don, about 5 years ago, the same size hail hit here, piled up about 4 inches on the lawn, put 135 dents in the Grand Caravan and shattered the back window. Took it to the body shop owned by a friend, he had an expert in this kind of damage working for him and after a couple days, called me and some come get your car. Not a single dent remained an the back window had been replaced. The body tech actually used a special, custom made tool with which he actually rubbed the dents out from the inside, didn't loose a speck of paint and the entire bill was covered by insurance. He said sheet metal has a memory and if you have the patience and knowledge, you can restore the shape very easy using the right tool. I was amazed.

Here's a video of how it's done:



Good luck,
