its not as simple as it sounds, the dents have creases, and therfore need to be worked out w/ a hammer and dolly
shoving the dent out with brute force will only compound the problem
damn, do me a favor, go on the audi boards and see if you can find someone with a picture of a disassembeled door, showing the internal structure, post it up and i can advise you from there as to what it will take
and oh yea, audi sheetmetal doesnt take kindly to slide hammers … usualy makes it look like you tried to fix a dent with bird shot in a shot gun
