I had pretty good success with my "Hillbilly Bumper Press".

Here's the picture.

The bumper is 5/16 thick. With a combination of heat, and 8 lb hammer, and pressure from a 20 bottle jack; I was able to massage out most of the dents. With this method, correcting twists is a little bit more difficult.

Dog help is optional.
