I have to add my 2 cents to this build. I have been reading it with much interest. I purchased an old smelly truck, it was an unmolested original truck with great patina. I was at first gonna try to do it all over, the rat rodder in me said maybe not. I just couldnt, it was an old very solid truck. So I am doing as you are, fixing as I go, I dont wanna paint it except where i have patched it. I love the look of aged stuff, I was thinking maybe we could call them "resto rats"..whatya think???....old stuff that is ratty but still original...sorta...nothing like the smell of an old truck cab..kinda brings me back to my childhood...
