Any spar varnish with UV protection will work. Normally you pay more for stuff with more solids, more solids will achieve the same coating thickness with fewer coats. I'd buy the heck out of spar varnish with UV at 6 bucks a gallon.
Look for the stuff recommended for use on exposed exterior wood like front doors, your basic urethane (as opposed to spar with UV) will probably wear off very fast and the UV additives are important to the longevity of your epoxy coatings.
