I used a polyurethane based enamel that is made by gliden for $16 a gallon. You can get it at places like Home cheapo or lows. It covers nicely and can be done in 2 coats over resin sealed wood or 3 with plain dry wood. It finished to a nice gloss and is color fast wet, dry, hot or cold so far as i've experienced. It is very durable because it is made for painting on decks and foot traffic areas.
