3M™ Silicone Paste is a non-hardening, water resistant, silicone based compound designed to lubricate, protect surfaces from oxidation and serve as a dielectric compound. It is a high viscosity paste that will remain in place for a long period of time. It can be applied heavily to help seal out contaminates and environmental elements that lead to oxidation and corrosion or it can be spread thin to leave behind a virtually unnoticeable film. A brush is permanently attached to the top to make applying it more convenient.
