It penetrates into tight spaces to lubricate small high speed bearings and between tight surfaces. It provides rust and corrosion protection even under the most adverse conditions. Also works great on folding knives. It comes packaged in a 1 ounce bottle with a precision needle applicator for one-drop applications allowing you to put just the right amount of lubricant into hard to reach areas.
