If you' ve got the equipment, I don' t think there' s anything much better than Fullerplast. I sprayed my longbow with Minwax Spar Urethane and it' s okay, but I' ve got scratches in it and areas on the edges of the working portion of the limbs where the finish is cracked up and rough. I' m going to sand it down and have a friend put Fullerplast on it for me. It' s a lot tougher than polyurethane.
