    Minwax® Water Based Helmsman® Spar Urethane

    Water Based Helmsman® is a crystal clear, water-based finish that is specially formulated to protect wood against nature's toughest conditions. Water Based Helmsman forms a protective barrier against rain and moisture and the ultraviolet absorbers found in Water Based Helmsman reduce the graying and fading effects of the sun. Because it's water-based, it has little odor, dries quickly and cleans up easily with soap and water.
