Slayte, make sure they neutralize that acid, I've seen some horror shows lately. After two and three years it starts to show up at seams - one in particular is the horisontal one on the firewall and the seam between the upper and lower cab. It starts to bleed. Look real close at all your options. As far as priming - I rolled my cab onto the fire wall on a piece of plywood and sprayed the bejesus out of everything I could see on the bottom, I waited for it to flash and did it all again. Then rolled it back and leaned it way over to one side and then the other while I sprayed lots of primer on it. I've had mine on the road for five years and she still gets lots of great comments ... but I didn't get it dipped, I had it sandblasted. Nowadays I would look closely at soda blasting and the use Zero Rust ... I used SB & ZR on my '51 frame and cab that I'm working on - seems great I'm really happy with the results.
