303 Aerospace Protectant is a water-based UV protectant for vinyl, rubber, plastic, finished leather, gel coat and fiberglass. It leaves a natural matte finish and helps reduce fading, cracking and discolouration while making treated surfaces easier to keep clean.
Use it for compatible dashboards, door panels, exterior trim, vinyl boat seats and spa covers. Choose it when you want a clean, understated appearance without an oily-looking shine.
Benefits and suitable surfaces
- Helps protect UV-sensitive materials from sun exposure.
- Repels dust, dirt and staining on properly treated surfaces.
- Suitable for finished leather, vinyl, rubber and compatible plastics.
- Use on vinyl convertible tops; choose 303 Fabric Guard for compatible outdoor fabric tops.
How to use
- Clean the surface first and let it dry. 303 Multi-Surface Cleaner is an option for compatible water-safe materials.
- Work out of direct sunlight. Apply to the surface or a clean microfiber towel, controlling overspray.
- Spread evenly, then wipe completely dry with a clean microfiber towel. Do not leave it to air-dry.
- If streaks appear, remove excess with a damp towel and immediately buff dry.
Aftercare
Keep treated surfaces clean and inspect them regularly. Follow the reapplication interval on your bottle; 303's application directions recommend every 3–5 weeks for continued protection. Complete buffing is important for an even finish and lasting performance.
Where should it not be used?
Do not apply to unfinished leather or suede, fabric or canvas, flooring, clear plastics, gauge panels or headlights. Check the material manufacturer's care instructions before treating an unfamiliar surface.
