Boeshield T-9 was developed and licensed by global aerospace leader, The Boeing Company, to fill a need for high-performance, long-term metal protection and lubrication. T-9's rust preventative spray uses a unique formulation of solvent carrier and paraffin wax coating engineered to penetrate crevices deeply, displace moisture, dissolve minor corrosion, and leave a clean, waxy coating with lasting durability-without using Teflon, silicone, fluorocarbons, MEK, or acetone. Whether it be automotive, bicycle, industrial, lawn and garden, marine, RV or tools, T-9 continues to be the best option for rust prevention and waterproof lubrication.
