Practice, go slowly, brace, brace, brace(if surgery is substantial), and read Robert’s sticky MIG welding tips in the Paint and Body Forum. Good stuff.
You’ll never be able to do it if you don’t try. You can do it. I actually sold a truck because of my nerves regarding sheet metal work. But after a lot of practice, mistakes, and learning I won’t hesitate now to cut out rust. I’m still a “beginner/novice” and haven’t tackled the “expert” stuff, but for cab corners, floors, etc, you can do it! Be prepared for reproductions to not quite fit as original and they will need some finessing.
As my old, coyote trapping, hard drinking, best farmer I knew, bear of a man neighbor used to say,”It’s just metal. Weld it back together if you screw up!”
