In 1958, the USS Nautilus, the world’s first nuclear powered submarine, made its historic journey and ran into a major system failure which threatened the entire mission. The crew of the Nautilus determined there was a leak in the Nuclear Submarine Condensing System.  For many hours the crew searched to locate the leak with no success. Commander Anderson came up with a idea that could possibly stop the leak!

After consultation with Washington, the Commander sent his crew into Seattle wearing civilian clothing in order to buy several jars of “that stuff you pour into automobile radiators to stop leaks.” He continued… “What do they call it…BAR’S LEAKS?”  Later the crew returned with 140 quarts of Bar’s Leaks Radiator Stop Leak.  After introducing Bar’s Leaks into the condenser system of the USS Nautilus, the leak was stopped. The mission was saved! 

In his book, Nautilus 90 North,

Commander William R Anderson gives his testimonial of his (and his crews) experience of the leak stopping power of Bar’s Leaks in Chapter 13

Commander Anderson claims that his crew are the “most enthusiastic proponents of Bar’s Leaks in the world!” Bar’s Leaks have been used for stopping and PREVENTING automotive and industrial cooling systems leaks!
