A new applicator on the Permatex Dielectric Grease in an Automatic Tube, No. 81153, makes it easy to dispense just the right amount of dielectric grease to electrical connections in even the tightest spots. The dielectric grease formula required for today's high-energy ignition and electrical systems protects electrical connections and wiring from salt, dirt and corrosion while extending the life of bulb sockets. The grease prevents voltage leakage around any electrical connection and also prevents spark plugs from fusing to boots. The 3 oz. can features a screw-on straw for improved accuracy.
