Waterlox Original Sealer/Finish, 1 Gallon

Best oil-varnish blend. The highlights are tung oil penetrates the wood before the varnish component builds a film on top and deeper gra in enhancement than pure surface film finishes. Keep in mind that long cure time -- 2 to 3 weeks for full waterproof cure.
