I have used Coverite 21st Century Clear Coat on my last 3 ARF's (H9 Funtana, DP Ultimate, Seagull Harrier) and been very pleased. I use it to seal the edges of the trims to prevent them from peeling off. It is very easy to apply and comes in a typical spray paint can. It has a higher gloss than Ultracoat and Monokote.
