For any closed area you have access to, there is a spray can product called Rust Through. Just what in means. After spraying you can weld through the coating. Available at paint and some parts stores. Fab your own panels!! That's a challenge. I made a trunk extension for 57 300. Lot of work, turned out good if a say so myself. Gratifying. Anyone needing my updated parts list, mail and ask.

I chose to fabricate my H trunk floor myself and so far it has come out OK. I did spend 4 - 6 hours hammering in the stiffening beads with a homemade tool and hardwood die. ( A 1/2" core router bit made a nice groove and two pairs of grooves reduces shifting the sheet metal.) Shortly I'll attach and reweld the two bottom stiffeners and this is where my question is; is that enclosed area painted / protected? At the factory would that inside area get coated when the body was dipped? I could paint / protect inside first and then grind / remove paint / weld or I guess I could weld first and later pour some thinned paint through the end openings and gas tank strap bolt holes. I have wondered how restorers deal with these sorts of enclosed areas. Thanks for any advice.
