well...i'm curently doing bodywork on my car....i backed into a truck one time...it was dark and the angle was weird ok!....but anyways that was a pretty nasty fender bender....i ended up taking a jack and supporting it all up so i could jack out the dent....when it was fairtly good i just took a hammer and wacked out some of the big dents....nowi'm filling all my dents with body filler....and soon will paint my car too....hope it works out....the front fender i would suggest driling holes and pulling out the dent...u can even just screw in some screw in the dent and pull it out with pliers...and then just fill or fiberglass what needs doing....if its the rear fender and if u can see the dent from inside the trund then bang it out by all means....then do whatever u can to pretty it up....by the way...this isnt coming from a pro....but it should work out fine cause thats pretty much how the bodywork on my car is done....hehe
