If you want to get the dents out of the part that is double thickness, you can try the stick on dent pullers that Jerry mentioned (aka Paintless Dent Removal or PDR kit,) although with the thickness of vintage steel that was used on our trucks, I had absolutely NO success with that. What I did use was a borrowed stud welding gun and puller. I got a couple of roof dents above my rear window out to just need a skim of filler. The same principle as the PDR, but more robust. You do have to grind off the pins afterward.
