When you guys did your bodys, how did you go about rustproofing. I have torn this thing completely apart, drilled out all the rivets and have been just bolting it back together temp and priming it (since those of us who live in the NY State rain forest see our steel rust almost overnight) as I repair all the rust damage (and as you can see she had a lot!) What do you think about just welding it all back together and smoothing all the rivet holes out, think it will make any difference structurally (as in Henry"s built in body flex)
