Lets say you are going to tear apart a door or trunk, or whatver.. blast it or dip it clean, and put it back together. Or maybe even you are constructing an inner panel from scratch.

What is the best coating to apply... keeping in mind the pieces still have to be welded.

Now let's assume the welding damaged some of the coating. Now you can't get to it too good... but you want to seal out the rust.

suggestions please.

Thanks
