303 Aerospace and Marine Protectant Spray

Overview

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)

As an NRVIA-certified inspector, I often recommend 303 Aerospace Protectant for rubber roof maintenance, slide seals, and interior vinyl care. It helps extend component life and keeps materials looking new. Its non-silicone, water-based formula makes it safer for long-term use compared to traditional tire shines or silicone sprays that can cause material degradation.
