Found some rust

Thanks for the info on the pan being spot welded.

As for it just being surface rust, for the most part it is but there are about a half dozen pin holes in the rust and one hole about the size of the tip of my pinky finger. The picture was taken after wire wheeling it. That's why I was thinking of using the fiberglass. Just to fill in the few holes I do have.

This is a full restro (kinda) it's a 74 Dart, 73 Duster front end, 2001 durango 5.9. So kind of a Scamp. It's for me as I don't think the year / model will ever be worth much but I don't want to build a beater or Rat Rod, I want something nice.
