I may be able to get Dupont at Oreily Auto Parts. I just remembered I have bought Nason epoxy primer there before and used it on my truck and top coated with Sherwin Williams. The Fulthane 2K urethane is in Dupont"s Nason line I think.
I would like to use the surfacer on the whole tractor if its ok. I would like to make the whole thing super slick.
