paint for cab underside?
 

I'm doing a full floor pan on my 72 c10. It's going to be pro-tour, driven in good weather, not a museum truck. I assume the best thing to do is prep and coat it while it is on it's back then mask it to the floor for body paint. Correct? What is the best product to coat the underside of the cab? Just paint? POR15? Paint then rubberized undercoat?

On a build like that the metal is gonna be all clean and fresh why not sand prime then paint it with the regular base coat clear coat that the rest of the truck will get? Out of mine [5 builds] they will be a wide range of builds from common cheapie [as cheap as a frame off rotisserie can be] to double throw down builds I plan on painting the floor on some of mine with the same BC/CC as the rest of the truck. Some of the others will have a bed liner type stuff sprayed on the underside, and then one more is planned with a tintable spry on liner to go under the cab and inner fenders and beneath the bed.I think the painted underside will look super slick while the sprayed on liner type stuff will be most durable and the one that will have paint mixed in will look good be durable and hold down the most road noise.Now if your wanting to look more to the noise reduction and simplicity the regular undercoating is reliable and hard to beat.
My vote would be BC/CC underneath Jim

I'd spray it with lizard skin to cut noise heat and vibratin from the bottom

We went to bare metal, expoxy primer, then lizard skin. We'll see how long it lasts, but it looks good and seems to work well so far. Did this on both sides of the floor pan.

I bought lizard skin but havent used it yet. Good for both sides? Wondered how it would hold up on bottom.

Did you guys use the lizard insulator or sound control?

Re: paint for cab underside?
 

If using the skin I think isolator for the bottom and sound control for the inside. jim

We did both sound control and ceramic insulation on both sides.
