What about using a tung oil finish, either gloss or matte, for exterior wood that is constantly exposed to the weather? The benefit would be that all you need to do is scrub it down with steel wool and apply new coats as needed. Also, is it advisable to use western red cedar for such things as
hatch boards and the battens that hold them in place. I know it is not as strong as teak, but how strong does it need to be for
hatch boards?
