PREP-A-LUBE II is a red non-melt Bentone spray grease with penetrating action. It actually removes grit, grime and old grease when applied. PREP-A-LUBE II sprays out as a liquid penetrant then cures to a thick, non-melt, pressure-resistant coating that protects and lubricates equipment. It holds up under wide extremes of temperature (-40°F to +500°F) and extremes of pressure, will not run or liquefy under heat and will not be washed away by water or steam. PREP-A-LUBE II also resists acids, oxidation & dirt and prevents rust and corrosion.
