WD-40?Specialist?Water Resistant Silicone Lubricant safely lubricates, waterproofs and protects metal and non-metal surfaces, including rubber, plastic and vinyl better than leading competitors. Our silicone spray dries fast and leaves a clear, non-staining film that doesn't stick or make a mess, so it won't attract dirt. Effective in a temperature range from -100degreeF to 500degreeF, it's ideal for use on cables, pulleys, guide rails, valves, linkages, hinges, locks and more, and is 50-state VOC compliant 4 BALL WEAR The test and what it means: This test measures the wear protection of a fluid on a metal surface. A steel ball is pressed with force against three stationary steel balls and is rotated at 1200 rpm for 60 minutes. WD-40 Specialist Water Resistant Silicone is far superior to the competition leaving the smallest scar, representing its ability to protect your machinery and other moving parts better than the rest. EXTREME PRESSURE The test and what it means: This test measures the load carrying properties of a lubricant. WD-40 Specialist Water Resistant Silicone demonstrates that it is able to withstand higher pressure than the leading competitors!

Proper lubrication of metal mating surfaces is essential prior to starting a new or rebuilt engine. Ultra Slick adheres to component surfaces to prevent scuffing and galling during initial start-up. This high quality formulation meets or exceeds OEM performance specs for engine assembly lubricants.
