Harmony Gunwale Guard is the best way to protect your wood canoe gunwales and decks. It's a deep penetrating finish that binds to the wood structure and prevents rot, UV deterioration, and retards mildew. Applied periodically, Gunwale Guard will keep your gunwales looking showroom new or better. For natural gunwales.
Ordered a can when installing my new wood gunwales on my 1982 Mad River canoe. Worked great! I could see the water beading off of the gunwales after the very first application. After 3 coats, the gunwales are perforing great in the water. I plan to reapply twice a year and will be ordering more.
