303 Marine Aerospace Protectant – 16oz

The sun cracks seats, fades plastics and dries out rubber. 303 Marine Aerospace Protectant blocks that UV and dries to a clear matte finish, so the seat doesn’t end up slippery and nothing looks greasy.

The 16 oz bottle is the one-bike size: seat, side covers, rubber parts and your helmet, with plenty left for the next few months.

• Safe on vinyl, rubber, fiberglass, carbon fiber, plastics and finished leather.
• Made for helmets, visors and goggles, tires and rubber seals.
• No silicone oils or petroleum distillates.
• Restores lost color and luster, and repels stains.
• Spray on, wipe dry. Made in the USA.

Where not to use it: suede or other unfinished leather, fabric and canvas, flooring, clear plastics, gauge panels and headlights. So it’s not for a fabric motorcycle cover; that’s what 303 Fabric Guard is for.

It’s also in our Winter Storage Kit and Cover Care Kit. And if your bike sits outside, cutting the sun exposure in the first place helps most: a Speedway Shelter keeps it in the shade between rides.

Can I use 303 on a motorcycle helmet visor?
303 lists helmets, visors and goggles as good uses for the Marine Aerospace Protectant. It’s not for clear plastics like gauge panels or headlights, so test it first.
