303 Marine Aerospace Protectant – 32oz

Got more than one bike to look after, or a boat and a trailer too? The 32 oz bottle covers all of it. 303 Marine Aerospace Protectant blocks the UV that fades, cracks and ages vinyl, rubber and plastic, and it dries to a clear matte finish.

Here’s where the bigger bottle earns its keep:

• Motorcycle and trike seats, plastics, rubber and helmets.
• Trailer and toy-hauler tires.
• RV EPDM rubber roofing and slide-out seals.
• Boat seats, Hypalon inflatables and wet suits. 303 says it even keeps inflatables from sticking together in storage.

It’s free of silicone oils and petroleum distillates, safe on vinyl, rubber, fiberglass, carbon fiber, plastics and finished leather, and it restores lost color while repelling stains. Spray on, wipe dry. Made in the USA.

Not for: suede or unfinished leather, fabric or canvas, flooring, clear plastics, gauge panels or headlights. For fabric covers, use 303 Fabric Guard.

Sun is the slow killer of anything parked outside. If your bike lives outdoors, a Speedway Shelter cuts the exposure, and our guide on how to make a motorcycle cover last has more on UV.
