WD-40 Co.’s Spray & Stay no-drip, no-mess gel lubricant is the ideal solution for vertical surfaces and moving parts where lubrication needs to stay put. The gel-like formula is engineered with self-healing technology that softens to lubricate when there is friction. When friction stops, it solidifies again to protect against rust and corrosion. The gel prevents rust for up to one year, WD-40 notes.
