Cab undercoating????
I'm just finishing up a cab underneath restructure and floor replacement on my 70 C10. Wondering whats the best for protection from underneath once I'm done??? Some type of undercoating, prime and paint or something else??? This is not a daily driver but not a show truck either. It will be parked in the winter so it will not see any snow/salt. What do you think????

If you can get it clean enough, I'd suggest POR-15 or something like it. Undercoating doesn't protect from rust that well--JMO

I sandblasted, used epoxy primer, some rubbery stuff that is supposed to be painted over, more epoxy primer and a couple of coates of rustoleum. I still wouldn't want to use it in the Winter. If I had it to do again, I would have had the bottom of the cab and the floor powder coated while the cab was bare.

We variprimed mine, then with a sealer, then enamel paint, then undercoated.

I used etching primer and then used spray in bedliner ... sealed up nice and quiet now.

I second the por15 idea. It protects against further chances of rust plus it drys to a rock hard surface so it won't chip off once applied.

The undercoating was still on the bottom of my cab, so I cleaned it up and got some 3M spray on undercoating. If you aren't driving in the winter something like this will last for a long time. I did a truck in '89 this way and last time I saw it was still nice a year or two ago. Just make sure you aren't spraying over rust.
