303 Marine Aerospace Protectant – 1 Gallon

If you go through 303 Aerospace Protectant fast, buy it by the gallon and refill your spray bottle. This is the size for detail shops, dealers, RV and boat owners with a lot of surface to cover, or a garage with several bikes.

It’s the same 303 Marine Aerospace Protectant: UV blockers that keep vinyl, rubber and plastic from fading, cracking and aging early, with a clear matte finish and no greasy shine.

• Safe on vinyl, rubber, fiberglass, carbon fiber, plastics and finished leather.
• Good for motorcycle seats and helmets, tires, RV EPDM roofs and slide-out seals, Hypalon inflatables and wet suits.
• No silicone oils or petroleum distillates.
• Restores lost color and luster, repels stains.
• Made in the USA.

Keep it off suede and unfinished leather, fabric and canvas, flooring, clear plastics, gauge panels and headlights.

Tip for refilling: pour into a clean, labeled spray bottle so nobody mistakes it for a cleaner. Smaller sizes (2 oz, 16 oz and 32 oz) are in our Storage Maintenance section.

For a bike that lives outside, shade does more than any spray. See which Speedway Shelter fits your bike.

Common Questions

Why buy 303 Aerospace Protectant by the gallon?
For refills. If you’re treating a boat, an RV roof and a garage full of bikes, the gallon refills smaller spray bottles.

Can I use 303 Aerospace on an RV rubber roof?
Yes. 303 lists RV EPDM rubber roofing as an ideal use, along with tires, slide-out seals and inflatable boats. Spray on and wipe dry for a clear matte finish.

What surfaces should 303 Aerospace not be used on?
303 says not to use it on unfinished leather like suede, fabrics such as canvas, flooring, clear plastics, gauge panels or headlights.
