Super55,
You won't regret it. I tried mine on those cab dings last week with a lot of success. I'm trying to use as little bondo as possible. I was able to pull small dents so that only high build primer will be necessary. I borrowed some techniques from the paintless dent removal guys. Here's what I found that works:
I polished the area so that I could watch the reflection while I pulled the dent. A fluorescent light works great for the reflection.

I only used a short pulse to weld the studs. The studs can be twisted off and reused a couple times.

Instead of using the slide hammer, I made a "bridge" tool. It's a steel bar with a small hole that is supported at each end about 3/4" away from the surface. The welded stud pokes through it and I pull it slowly with a pop rivet gun. Very controllable.

A dent the size of a quarter may require 8 pulls or more to progressively bring the surface up where it should be.

Use a sanding block to scuff it lightly to see if you have any high spots. Tap them down a little if necessary.

When you're satisfied, lightly draw file over the area.
