I have a nice dent on my 65 Gal. It is approx 12'' long and goes from body line to body line on the pass front fender. It starts at the top and goes at a diagonal 45deg towards the second body line down on the fender if you know what I mean. What would be my best plan of attack on this? It isnt real deep. You can barely see it from the inside of the panel. Would a body hammer be my bet?
