Originally engineered for aerospace and aviation applications, 303 Aerospace Protectant has found its way into millions of homes for day-to-day use. Unlike many protectants that leave greasy residues, Aerospace dries to a clear matte finish without a trace of oil. There’s a lot of power packed into this one product. A premium surface treatment, Aerospace not only protects against fading, discoloration and cracking from harmful UV rays, but repels dust and stains, too.
