Yes, I feel Epoxy is THE product for "hard parts". What I mean by that is frames, chassis componants, rad support, that sort of stuff. Wash etch, epoxy prime, top coat with a single stage urethane. That is the best system out there for the buck. No sanding, just three applications of product and the corrosion resistance is super, the durability of the top coat is super, it is just a great system.
But if you have to sand epoxy, my love for it starts to drop. Urethane is SO much easier to work with.
