Dent Removal HELP!!!

[OklaHemi]

While the truck is on stands, a bucket list has be created to get it back into shape. Getting a few dings removed is one of the task on the list. There are at least six that need to be addressed: One on each door and two on the tailgate. They are all quarter size or smaller. Some are not reachable due to door frames and other obstacles. I have no dent removing experience but have read all the gimmicky stuff, what really works? Or should I save my time and take a trip to the auto-surgeon?
