Protecting a Sunbrella With 303 Fabric Guard: 303 Aerospace Protectant should be applied to Sunbrella fabrics after each thorough cleaning, which typically removes the original finish and reduces the fabric's water repellency.

• Allow Sunbrella to completely air dry.
• Apply 303 Fabric Guard in a well ventilated area following instructions on the container.
• Apply 303 in a thin, even coat and allow fabric to dry completely.
• Apply a second thin, even coating of 303. (Two light coatings are more effective in restoring fabric water resistance than a single heavy coating. A 15-ounce bottle provides coverage of up to 50 square feet of fabric.)
