The Tri-Flow Superior Dry Lubricant is an exceptional formula designed for dusty and dry conditions. By using a drip bottle application, and a straw for easy access, hard-to-reach moving parts can be penetrated deeply. The lubricant comes in a combination of paraffin wax and high-grade petroleum oil that allows it to first go on wet but then set up into a dry, wax-like coating, so it won't attract grit and dirt. Perfect for dirty or dusty conditions, but still provides adequate wet weather performance.
