303 Marine Aerospace Protectant – 1 Gallon (Case of 4) – UV Protectant & Surface Restorer (30370CASE)

Protect and extend the life of your boat’s surfaces with the 303 Marine Aerospace Protectant, now available in a 1-gallon case of 4 for high-volume use and long-term maintenance. This industry-leading UV protectant spray is trusted by marine professionals to restore, protect, and preserve a wide range of surfaces exposed to harsh sun, salt, and environmental elements.

Formulated with advanced UV screening technology, 303 Aerospace Protectant helps prevent fading, cracking, chalking, and discoloration, while leaving behind a clean, non-greasy matte finish—never oily or sticky.

Core Technology & Performance

• SPF 40 for Marine Gear: Originally developed for aerospace applications, it provides a powerful UV barrier that prevents fading, cracking, and premature aging of materials exposed to intense sun.

• Non-Greasy Matte Finish: Unlike silicone-based products, it dries to a clear matte finish that is non-slick and won't attract dust, dirt, or sand.

• Surface Restoration: It chemically bonds to surfaces to restore lost color and luster, making weathered vinyl, rubber, and fiberglass look new again.

• Safe for Specialized Materials: Formulated to be 100% free of grease-producing oils, it is safe for Hypalon inflatable boats, carbon fiber, Plexiglas, and wet/dry suits.
