A while back my car (2k Cougar) got whacked by a '68 Chevelle. I was parked and the little old lady was trying to park next to me. She pretty much caught just behind the passenger door & put a nice 12" crease from the bumper. The sheet metal also indented quite a bit as well. I pulled the interior panel & speaker off and was able to get to a majority of the area with ease. Enough to push the largest part of the indent back out at least (no pics avail). I tried some light tapping & pounding with what little room I had to work with and didn't do much. I have a dent puller that I'm going to try on the remaining portions to see if it'll work better now, but I have a guy I work with who has the tools for hammering out dents he'll lend me. Are there any sites or recommended books I can check out that will help me get most of this out?
