303® Marine Fabric Guard – 16 fl oz Protector for Marine Fabric & Outdoor Surfaces

Q: Can I use 303® Marine Fabric Guard on Sunbrella® fabrics?

A: Yes. It is the only fabric protector recommended by Sunbrella® for restoring water and stain repellency.

Q: Does this product change the feel or color of the fabric?

A: No. It maintains the original color, texture, and breathability of the fabric while adding protection.

Q: How long does the protection last?

A: Typically 6–12 months, depending on sun exposure, weather conditions, and frequency of use.

Q: Can I use it on vinyl, rubber, or plastic?

A: No. This product is designed specifically for fabrics. For vinyl or plastic, use 303® Aerospace Protectant instead.

Q: Is it safe for use indoors?

A: Apply outdoors or in a well-ventilated space. Allow the treated fabric to dry completely before indoor use.

Clean fabric thoroughly and allow it to dry completely before application.

Shake the 303® Marine Fabric Guard bottle well.

Spray evenly over the fabric surface until fully covered but not oversaturated.

Use a soft brush or cloth to work the product into the fabric if needed.

Allow fabric to dry for 12–24 hours in a well-ventilated area before exposure to moisture.

For maximum protection, reapply every 6–12 months or as needed depending on sun and water exposure.
