I live in SC and have an old Victorian home with a Cyprus plank floor. Sun and moisture are problems. I would like recommendations on what to use for a finish. I put the floor down 10 years ago and used a clear Spar Varnish oil base finish. The sun peeled the areas where it hit the porch. I have just sanded the floor competely and need to put some kind of finish on it. Am at a loss on what to use that will hold up. The planks are not tongue and grove. Would like a clear or natural finish. Any help will be greatly appreciated. Thanks Howard King
