Without a semiautomatic welding machine, you can patch up holes in the car body just as well. Of course, this takes more time than re-welding a rotten place. But when there are no other options, this is a good method. I decided to show the full process, from removing rust, sealing the hole with fiberglass, to sanding it down with sandpaper under the primer. ≛±☼⋆↯
