Rian,
Here are some pics of my repair. If I was great with metal work I could have pulled this off with no bodywork. But I'm not.
Rot cutout. Rust inhibitor sprayed on metal beneath. The underside of mine was still solid. And this rusted right where the brace underneath traps all the dirt and crap. I am going to seal this up with seam sealer when I get ready to paint it.

Cleaned up. Not the best.

A little bodywork to fix that mess. I used some bondo I had on hand. I may end up grinding it all of and using some of the new Evercoat. I got. Hope these pictures help you.
