2k urethane or epoxy primer?

Epoxy sticks, use that first, urethane is a finish primer that you use over the epoxy and under the finish coat. Make sure you paint over the epoxy within the recoat window,usualy about two weeks.

That's what I was trying to get across daredevil. Like he said, just make sure you shoot within the recoat window.
