Silicone Repair Tape
This tape is unique. It has no adhesive; it's just pure silicone. When you wrap it around something, the silicone essentially welds to itself to form a single flexible unit. No gaps, no slipping and no end to come undone. Silicone tape is amazing stuff: It's an electrical insulator and it resists just about everything (oil, solvents, acids, salt water). It's heat-proof to 500 degrees F and flexible at arctic temperatures. You can use it to fix electrical cords, wrap cables on a trailer and make a heat-proof grip for a frying pan. There are stories of people using it to make gaskets, repair high-pressure hoses, and even make an emergency fan belt by wrapping the tape around rope. In short, it's a miracle worker. It has only one drawback: the price. A 12-ft. roll, 1 in. wide, is about 10 bucks. One brand is Rescue Tape and it's available online.
