White grease (often sold as White Lithium Grease) is a lubricant that sprays on as a liquid and sets as a thick, white paste. Its distinct color serves as a visual indicator, allowing you to see exactly where it has been applied. It is famous for its water resistance and is non-corrosive. It is ideal for metal-to-metal applications like bonnet latches, door hinges, and sunroof rails where you need a lubricant that won’t run or drip in hot weather.
