Originally created by Boeing Aviation to combat corrosion in aircraft components, Boeshield T-9® is used today to protect against rust and corrosion on a wide variety of items, including workshop power tools. It provides superior corrosion protection and waterproof lubrication in one easy-to-apply, long-lasting formula. Just spray it on and it dries to a thin waxy film that clings tenaciously to metal surfaces. Leave a thick coating for additional rust protection, or spray on and wipe off for both rust protection and low-friction sliding on cast iron tops, such as those on jointers, table saws and router tables. An application of T-9 every few months will maintain the rust-inhibiting barrier.
