T-9 was developed by The Boeing Company for use in airplane construction - with its critical requirements for reliable function, corrosion resistance, and longevity. A revolutionary product when it first came to the marketplace, T-9 quickly became known as "Boeshield". What sets Boeshield apart from other similar products is that it not only lubricates and penetrates frozen fasteners, it also leaves a tough, long-lasting film that continues to protect and resists washing off.
