Containing ultraviolet radiation absorbers and anti-oxidants, ZAR is the ultimate in protection. ZAR's full- bodied formula brushes on like a conventional polyurethane for maximum durability and beauty. Goes on milky but dries to a rich, amber color. Ideal for exterior wooden surfaces, marine bright work surfaces (above water-line), stained exterior doors- including fiberglass and steel doors, natural wood siding, patio furniture, fences, gables and other wood surfaces exposed to direct sunlight and the harsh extremes of weather.
