303® Aerospace Protectant™ (Part of the Universal Range)

Originally engineered for aerospace and aviation applications, 303® Aerospace Protectant has found its way into millions of homes for day-to-day use on vehicles, sports equipment, patio furniture accessories and more. Unlike many protectants that leave greasy residues, Aerospace Protectant dries to a clear matte finish. And because it’s water-based, this protectant is safe to use on all products, from your vehicle’s paint job and leather seats to internal engine parts.

There’s a lot of power packed into this one product. A premium surface treatment, Aerospace Protectant not only protects against fading, discoloration and cracking from harmful UV rays, but repels dust and stains, too. Simply spray on and wipe dry for a beautiful, matte finish that protects your vehicle from road grime and favorite belongings from dust and soiling. Best of all, each application will last for months.

No other protectant beautifies as intensely or preserves as powerfully. Keep UV-sensitive materials looking new, year after year.

The most powerful UV screening formula ever developed with a SPF 40, regular use of 303® Aerospace Protectant™ provides 100% prevention of UV caused slow-fade.

303® Aerospace Protectant™ is non-toxic, silicone free and biodegradable. Lasts 4 to 10 times longer than other products. Water repellent so it doesn’t wash off. Prevents drying and cracking and keeps rubber, vinyl and plastic items pliable and supple. Restores lost colour and lustre.

Gives outstanding results on vinyl, clear vinyl, all types of rubber, finished leather, anodised aluminium, gelcoat fibreglass, sail cloth, painted surfaces and stainless steel.

303 Aerospace Protectant has many applications for use on non-absorbent surfaces, including:

Boat Interiors: Spray on your vinyl boat seats to prevent them from fading and cracking during boating season. Will also help keep them clean from dust, sand, and will help prevent those dreaded sunscreen stains.

Automobile Interiors and Exteriors: Use on your vehicle’s dashboard every 30-45 days, to protect it from the sun’s harmful UV rays, preventing fading and cracking over time. Spray on tires to make them look new without the greasy film. Use on your convertible top to keep it pliable and cleaning up easier.

Spa Covers: Use on your spa cover all year long! It will protect it from the sun’s harmful UV rays (which can cause fading/cracking) in the summer months, and in the winter, it will keep the material pliable and prevent it from drying out and cracking. 303 Aerospace Protectant will also help make snow and ice accumulation easier to remove/brush off as well.

Outdoor Furniture: Keep your plastic, metal, or wicker outdoor patio furniture from fading, cracking and chalking. It will also help repel dust, dirt and grime, that can quickly accumulate on your furniture during the enjoyable BBQ season.
