I used maple to inlay this bass on my cabin door along with various hardwoods we had in the shop. I coated the entire door (3 pieces) with a spar varnish. It is about 4 years old now and is showing a little discoloration around the edges. Its due for a sand and recoat. I think the epoxy would be great as long as the entire piece was coated. My door lives under a bimini top during the season and I store it inside for the winter. In this photo the bottom section is left out for ventilation.
