303 Products Marine Aerospace Protectant for Boat Vinyl — 16 oz Spray, UV‑Blocking Matte‑Dry Protection

303 Marine Aerospace Protectant is a non-greasy, UV-blocking spray that restores and shields boat vinyl, plastics, rubber and gelcoat for lasting appearance and protection.

Designed for marine environments, this 16 oz bottle delivers broad-spectrum surface care that reduces fading, cracking, salt buildup and staining caused by sun, water and airborne contaminants. The matte-dry formula rejuvenates colors and textures without leaving oily residues, making it suitable for both interior and exterior surfaces on boats, RVs, outdoor furniture and more.

How does this protectant stop UV damage and fading?

303 Marine Aerospace Protectant contains stabilized UV absorbers and antioxidants formulated to slow the breakdown of polymers and pigments. Regular application forms a thin, invisible film that reduces sun penetration and helps maintain the original color and flexibility of vinyl and plastic parts.

• Blocks UV rays to minimize fading and premature aging.
• Antioxidant components help prevent material brittleness and cracking.
• Leaves a matte finish to avoid glossy, slippery surfaces.

Which surfaces can I safely use it on?

This spray is versatile across many marine and outdoor substrates: vinyl, PVC, synthetic and natural rubber, plastic trim, metal, gelcoat, fiberglass and stainless steel. It’s formulated to be non-greasy and non-staining, so it refreshes both textured and smooth surfaces without altering appearance.

• Ideal for boat seats, dash panels, consoles and vinyl covers.
• Suitable for swim platforms, fenders, and plastic hardware.
• Can be used on outdoor furniture, RV trim and other exposed equipment.

How do I apply it for best results and how often?

Apply out of direct sunlight to a clean, dry surface. Spray an even mist and wipe completely dry with a clean, lint-free cloth; avoid overapplication. For ongoing protection, reapply every 3–5 weeks after routine cleaning, or sooner in extreme sun or high-salt conditions.

• Use after a dedicated boat cleaner for maximum adhesion.
• Apply in shaded conditions to avoid streaking and rapid evaporation.
• Allow surfaces to dry fully before exposing to water or heavy use.

What should I know about shelf life and safety?
