There is a company named "Dent Pro" out here in CA, they specialize in paintless dent removal. The tech comes to you and gives you an estimate. He was able to fix every dent and ding on the car except for those that were right over a cross member. Another idea, would be to sand down the hood, bondo then block sand. If you go to a VERY GOOD body shop, you'll never notice the difference. Bondo used to have a very bad rep, but now I see more and more of it and when it's done right, it can make small imperfections disappear. When I was young, I had heard that you could use dry ice to pop a dent. I just did a google search and came up with both "it works" and "it's a myth"
