303

303 Products are the industry standard for UV protection and surface maintenance, originally developed for aviation but now essential for marine and automotive use. Their lineup is divided between cleaners (to remove dirt) and protectants (to prevent sun damage).

Essential 303 Cleaners

Before applying any protection, the surface must be clean. These formulas are designed to rinse away completely without leaving a residue that would interfere with a protectant's bond.

• 303 Marine Multi-Surface Cleaner: This is a powerful, residue-free cleaner safe for all water-safe materials. It is the manufacturer-recommended first step for cleaning boat seats, covers, and even indoor/outdoor furniture.

• 303 Fabric & Vinyl Cleaner: A concentrated formula specifically designed for heavy-duty cleaning on Sunbrella fabrics, bimini tops, and automotive convertible tops. It effectively removes oil, grease, and bird droppings.

• 303 Mold & Mildew Cleaner + Blocker: Unlike bleach-based cleaners that can damage stitching, this formula safely removes mold stains and leaves a protective barrier to help prevent regrowth.

303 UV Protectants & Sealants

These products act like "SPF for your stuff." They are water-based and contain no harmful silicones, leaving a clean matte finish rather than a greasy shine.

• 303 Aerospace Protectant: The flagship product. It provides a massive boost in UV resistance for vinyl, rubber, and plastic. Use it on dashboards, tires, and boat upholstery to prevent fading and cracking.

• 303 Fabric Guard: This is the only product recommended by Sunbrella to restore lost water repellency to outdoor fabrics. It creates a powerful hydrophobic barrier that makes water bead off immediately.

• 303 Graphene Nano Spray Coating: A high-tech option for hard surfaces like paint, glass, and wheels. It provides up to 12 months of protection, significantly reducing water spots and making the surface easier to wash.

Quick Reference: Which 303 Product Do I Need?

Pro Tip: For the best results with Aerospace Protectant, wipe it completely dry. It is designed to be a "spray on, wipe dry" product; leaving it wet can cause streaking if it gets rained on before it fully bonds.
