for max life you want a wood stablizing clear epoxy primer (solvent based) - a few coats of real marine spar varnish and then roll and tip (or spray) two part LPU clear with uv blockers (most 2 part polys do not have uv blockers due to added cost). google ESP 155, India Spar Varnish, Acrylic Poly UV plus as examples of this sort of 3 layer clear coat system. No one product by itself will do 'everything' - paul
