Out-performs common electrical tape by sealing out moisture and dirt to virtually eliminate corrosion, which causes many electrical failures. Sticks to metal, wiring, rubber, vinyl and plastic, forming a tough flexible coating that dries at room temperature in 5 minutes. Handy applicator top and thicker formula is great for getting into tight places that just cannot be reached with ordinary tape. Use anywhere a dependable weather-proof connection is required.
