    Seal off electrical splices. This tape is thick and molds tightly around connections, filling in gaps and sealing out moisture. Plus, mastic rubber is self-healing—if it gets nicked, it settles to fill the gash and maintain the seal.
    Apply an outer layer of overwrapping tape (sold separately) for a stronger, weather-resistant seal and extra electrical insulation.
    No Facing—Conforms better than tape with a facing, so it seals around irregular shapes. We recommend you wrap this tape with overwrapping tape (sold separately) to protect the seal.
