do i undercoat my cab or just paint it? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just stripped one of my rustfree cabs to bare metal last month.I used two coats of Rustoleum Rust Stop primer and two coats of satin black Rustoleum.I'm not sure what color the truck will be and don't care if it matches since you never see it.I guess spray-on liner is good,but it scares me like undercoat and powder coat.If and when anything gets behind it,there it stays and eats.Paint crumbs off as the chip/scratch grows.Those other coatings are like a shell and I've seen worse damage because of those than without.

under coat because paint is not that strong up against rocks and sand and mud.trucks from the factory are under coated for a reason

I have done it both ways. If its a driver> undercoat. If its a show truck> paint. (And dont hit any rocks or gravel).
