Don't know what state you are in but I live in Michigan a own a log house. I order all my wood protection materials from Schroeder Log Home Supply in Grand Rapids, MN. There products are the best I found. www.loghelp.com 1-800-359-6614. They ship anywhere. For my decks I just use Thompson Wood Protector, but I power wash it every year and apply a new coat of sealer after.
