I decided not to hijack the thread about the frame-up restoration... What is the best way to protect the underside of the truck and treat some very minor rust that's starting? I'm in the "salt zone" here in Iowa and I want to get ahead of this before it becomes a problem. I had the factory undercoating, but it's half gone by now. Are ny of the commercial, Ziebart type things any good? People seem to like POR-15, but what a lot of work that would be to lay on my back and brush that all over the place. And how would it work with bits of rubberized undercoat still on there? Any other good options? I used to get under there and spray around with Rustoleum every year or two, but that's really not cutting it it doesn't seem.
