I agree that God made wood beautiful.Some of our competitors use T1-11 or treated wood for their portable buildings. We can do that, too, but we don’t think that you’ll be as happy with it. Any clear coat finish applied to a wood product has to be renewed every year or two. If you neglect it (and you will unless you are more motivated and disciplined than most of us), your beautiful natural wood finish will gray and weather and deteriorate.
