Well, I appreciate the information, Fatfenders. I'm not anywhere near that point yet, but I've looked under the dash and wondered how I'm going to handle that. Does soda blasting leave any residue? I have a friend who has sternly warned me not to sandblast the inside of the cab "because you'll never get it all out".
I think you've convinced me to use Zero Rust there for sure. I'm still not sure about the areas exposed to moving objects, like the inside of the fenders, the chassis, etc. The POR 15 worked really well, and I tested it with a hammer. Won't even chip when pounded really hard.
