As much as I like the epoxy, when painting a frame (if prepped correctly), I still think that brushed/rolled POR15 is the better choice. It's like a thick armor plate when it's done right. I'd have to put on many, many coats of epoxy to even come close to what two coats of the POR15 accomplishes. If it's something I'm going to sand or coat over, then no way I'm putting POR15 on it... I have no idea how flexible it is, but when I was driving out my front shackle bushings, I missed the bushing and hit the POR15 painted frame very hard with a 10 lb sledge hammer, and I could not see even a scratch where I had hit the frame!
