Fix 66 Cuda fender

I had a '74 Charger when I was a kid and I used a hammer and dolly. I seemed to get the best results by useing them both right off the get go and working the dent from the outter edge to the center going around it in a circle motion. It took along time and I did go slow so that I wouldn't do any more damage than what I was trying to repair. I would recomend ear plugs since my ears were ringing for what seemed like hours.
I would consider player1up's idea of practicing on a junk panel until you are more comfortable with the hammer and dolly.
