Thanks for the comments all, I appreciate the support.
Yeah on the stud gun, once the studs were in place, I found it helpful to lock the slide hammer on the stud. Then use a pulling force on the slide hammer/stud with one hand then lightly tap down the high spots around the dent with the other hand. On my doors because it's a 72 it has the door crash bar reinforcements so I couldn't get a dolly on the back side of the dent. Anyway just another way you can use the stud welder and slide hammer.
Yeah I hear you conv340. My doors are starting to look like that. I think part of my problem was not applying the body filler over a large enough area, meaning extending beyond the dents themselves. It's also a pain trying to make the main body line look nice. I bet it really sucks on a Challenger. All professional auto body guys must have Popeye forearms because after 4 or 5 hours of sanding, I'm really sore... either that or I'm a wimp.
