Since my reply was lost, I will say again...
Paintless dent repair is the best way to go. Before then, body shops used to heat the metal around the affected area. When the metal cooled, it shrunk and the dent dissapeared. The problem with this method is that over time, the paint would discolor on the affected area due to the application of heat.
You may be able to find a shop that will fix several of them for a fair price.
