MarK did suggest the spar urethane over Pelucid, but later in their test the finish still failed from the UV. Mine was just the Pelucid, no topcoat. Part of my problem might also be that it was sprayed instead of brushed. It didn't seem to penetrate the wood very well. Stiil, you might consider a bedmat for really sunny days to help prolong the finish life. I got one fairly cheap at the local Tractor Supply store. Besides, you never know if you might actually have to haul something.
