Spent the night blocking out the cab, and working on the roof, there were a bunch of little dents, and dings up there. I believe that it is nice and straight now.
With the next round of primer I will hit the inside of the cab, so I spent some time finishing up the floor, and hit it with a couple heavy coats dupont mastic epoxy, very tough stuff, and extremely corrosion resistant. My plan is to get some 2k high build primer surfacer on the cab this evening, then get the doors, fenders, and hood ready!
