i'm havin' a bit of a brain fart on an epoxy primer or something along those lines and hope someone can offer me some rolaids for the brain here. i ran across a product to coat my frame and underbody with, much like an epoxy primer, if i recall... it was available in a 5 gallon bucket for around $180.00 and advertised something like rhino lining or gator something.... one of those types of things... anyone run into this and recall what it was??? also, anyone used this stuff?
