I absolutely can't get a dent removed from a fender. Can see in the photo the area of the dent. It's about 1/16 - 1/8 inch low right now. I've tried to hammer and dolley it - the metal just won't move! I swear, hit it with a normal body hammer and it just won't smooth out any. Even hit it with a 2 lbs hammer, still doesn't budge. How do these guys on tv make it look SO simple? I've used torches to try and shrink it too, but doesn't seem to work real well. I heat up a small area - probably nickel sized - to a light red, cool with an ice water soaked rag. That has gotten rid of an oil canned area, but still just can't get it straight. What do I need to do??? I've literally spent hours hammering and it's minimally better then when I started.
