I think Don is right, I'm doing the same truck, I'm almost done with the second gallon of epoxy and ordered a third, I'll probably use half of that. and I bought 1.5 gallons of Automotive Arts SS 2:1+10% hoping to do two coats, but it was suggested that I go 3-4 coats if I want to cut and buff it, so I'll be ordering more of that too.
Good to know. I'm doing just the bed for now. Need to coat the sides, and the outside of the front wall with paint, and the sides, cargo area and front wall with epoxy.
Underside was done 2 years ago with POR. I know that seems to be a dirty word here, but it's on there solid and isn't going to peel off. Got a Jeep CJ frame done with it over 10 years ago and I'm not sure you could sand blast it off. You'd have to work at it, that's for sure. I read the horror story of it peeling off someone's job, that was surely a bad experience. Had to be something else to the story, or just a bad batch of the product. I know too many people that have used it successfully for it to be all bad.
Knowing what I know now, I'd use SPI epoxy on the underside if it wasn't already coated, but that ship has sailed, so I'll just leave it. It'd be a huge job to get it back off, anyway.
So I'm thinking I'll get 2 gallons of epoxy for now, and 2 gallons of 2k, with their respective activators and some reducer for that last coat of epoxy.
2 gallons of paint as well, I guess.
Any more thoughts on spraying clear over the SS black? Wondering how common that is.
