303 Marine and Recreation Fabric Guard restores lost water and stain repellency to fabrics. It resists water—even when you’re on the water—by creating a powerful shield to greatly increase repellency and protect against oil-based stains. Spray it on outdoor leather seats, boat covers, awnings, Dacron® sails and even outerwear. Keep all your favorite canvas crisp and clean for years to come. Unique and exclusive protectant for Sunbrella upholstery. For the best results, thoroughly clean the fabric with 303 Multi-Surface Cleaner before using.
