Size: 32 oz. Developed to protect and extend the life of marine fabrics including vinyl, polyester, canvas, and Sunbrella®. Contains UV and mildew resistant agents. Helps prevent damage from moisture, mildew, oil and grease stains, and other airborne pollutants. Heller Glänz Waterproofer is revolutionary because it combines waterproofing and protection and is longer lasting than other leading brands in the market place. It’s unique formulation allows it to penetrate the fabric further, therefore waterproofing from below the surface, which leaves the textured finish of the original fabric intact.
