Body help/advice needed

Thanks guys. I will cut the skin off and clean/sandblast the bracing. Then I will coat with Mar-Hyde then cover with Por 15. When I make my patch should it be a tight fit inside the cut out? I also got some brass to put behind the seems as I spot weld to help suck up some of the welding heat. I will go slow while welding and use more of a taching method so I dont put to much heat into the panels. Hope to start at it this weekend. Looks like this will be a very slow project.
Will post pics if I dont forget to take them as I go!
Thanks Rod
