Proxicast Pro-Grade Extra Strong 30mil Weatherproof Self-Fusing Silicone Rubber Sealing Tape for Outdoor Antenna Coax & Electrical Cables, Hose/Pipe Leaks & Emergency Repairs (2X 1.5" x 15' Rolls)

I used this product to wrap the junction between two differently sized antenna masts which were joined with a rubber sleeve and hose clamps. I needed to protect the hose clamps and keep water out of the junction. I used less than 3/4 of a roll and the junction was perfectly sealed -- including the hose clamps.

I live in Florida and the heat destroys electrical tape and even duct tape. I use this on car repairs now and it holds up like a champ.

Good for water proofing a repaired extension cord.

Easy to work with.
