WD-40 Specialist White Lithium Grease provides excellent lubrication and corrosion protection where there is heavy metal-on-metal contact, helping to reduce friction and wear on parts. WD-40 Specialist White Lithium Grease sprays on easily and leaves a handy white film for application visibility. It performs in all weather conditions thanks to its thick, non-drip, water-resistant formula, staying exactly where it's applied with the included precision straw, making it ideal for both indoor and outdoor use.
