Avoid polyurethane finishes as they can trap moisture below the surface of cedar.

Sand 3 inches past the end of the crack. After it sets examine the crack and if. Fill each crack with caulk then use a putty knife to scrape off the excess from around the edges. A full seal is important because any space that is missing sealant is more susceptible to water damage and chemical bleeding.
