Silicone Rescue Tape is a wonderful tool that is perfectly suitable for emergency marine repairs. The most popular application is repairing any leak on a radiator hose. Pull the tape tightly and start wrapping, and then the tape fuses to itself and seals the leak. Rescue Tape is a necessary tool to have on a vessel, and is critical to store in the toolbox. Rescue Tape is mostly silicone, therefore it is waterproof, unaffected by heat, and super strong. Rescue Tape is the most well-known brand of silicone tape on the market, and is used by the USA military. Rescue Tape is amazing for fixing leaks, waterproofing anything, repairing a radiator hose, and just about everything on a boat. I won't leave port without it.
