Boeshield T-9 was designed by Boeing Aviation as a corrosion inhibitor for aircraft components. Through licensing, this product is available to consumers and businesses. Boeshield T-9 is a combination of solvents, lubricants and waxes designed for penetration, moisture displacement, lubrication and protection.
Boeshield T-9 dries to a thin waxy film that clings to metal. Because it adheres to metal so well, it works directly on exposed metal surfaces. The product can be used in two ways to prevent rust.
A thicker coating works in places where additional protection is helpful such as on hinges, chains, undercarriages, cables and on items put into storage. To apply a thicker coating, just apply it to the surface and leave it.
