Bends are pounded out and cracks are welded= new fender N.O.S. ish.
You need a hammer, welder, bondo and sand paper. This is what life was like back in the last millennium. I find that my grass yard, with slightly moist dirt under the grass, is a perfect backing for pounding out dents in big stuff. A giant shot bag.
Tried a plastic kiddie pool of sand. Didn't like it and all the neighborhood cats pooped in it.
