Boogered door/fender edges repair?

I admit I never have had to deal with this, only maybe just a minor booger. I occsionally venture off into the dark side, in this case I have always wanted a 64 or 5 Merc Comet. 64 is one year model. Sheetmetal is not plentiful.
You know the drill, look for a cheap project!! It will be a solid fun driver, sorta a A/FX looking thing. Like said, solid not perfect BJ crap.

I found sorta locally, locally a 64 that the seller said was bought off some dopers, that replaced the front clip, and somehow manage to booger the edge of door and fender pretty darn good, they still open and shut but need major fixing. Wrinkled bad on edges about 1 inch in.

I imagine the fenders can be hammered back decent, but the door? I figure my best bet is cutting off the boogered skin in that area and butt welding in patches? Sorry I have no pics, its on my "maybe "list!
