Yes, I hear you on the contours! My left front fender was the worst as it apparently had a hard hit there in its life. I used my portapower to push the fender crunch back out, but the contours as you said, total pain! IT's not perfect perfect, but should be ok. If I had it to do all over again, I think I would have looked for a better project car~ meh, chalk it up to learning I suppose. I said I wanted a challenge
After welding this repair panel in, there was still a great deal of work making it acceptable. Kind of nerve wracking on this kind of repair.
