303 Aerospace Protectant is a premium UV protectant designed to restore and maintain surfaces made of vinyl, rubber, plastic, and fiberglass. Originally developed for aerospace and aviation materials, it’s become a go-to product in the RV, marine, and automotive industries for preventing sun damage, fading, and cracking.
Unlike silicone-based dressings, 303 leaves a matte, non-greasy finish that repels dirt and dust — ideal for both interior and exterior RV surfaces.
Key Features
- UV Protection: Blocks harmful UV rays to prevent fading, cracking, and premature aging of vinyl, rubber, plastic, and fiberglass surfaces.
- Non-Greasy Finish: Leaves a clean, dry matte appearance without attracting dust or residue.
- Multi-Surface Safe: Effective on dashboards, tires, EPDM rubber roofs, awnings, slide seals, and plastic trim.
- Water-Based Formula: Contains no petroleum distillates or silicone oils, making it safe for frequent use.
- Restores Appearance: Revives color and luster while protecting against weathering.
RV Use Cases
- Exterior: Rubber roof treatment, awnings, seals, and trim protection.
- Interior: Dashboards, vinyl seating, control panels, and plastic moldings.
- Storage & Seasonal Care: Ideal for UV protection before long-term storage or after washing.
- Maintenance Tip: Apply every 30–45 days for consistent protection; clean surface first for best adhesion.

Inspector's Note (RV Pro Solutions Insight)
My inspection training has taught me that exterior seals, trim, and exposed polymers usually benefit more from consistent care than from occasional heavy applications. With 303 Aerospace and Marine Protectant, I would start with a clean surface, follow the material manufacturer's care guidance, and apply only where the product is approved. A dry, non-greasy finish is useful around an RV because it is less likely to collect dust, but owners should still inspect treated materials for cracking, separation, or deterioration rather than expecting a protectant to correct existing damage.
