The Bar’s Leaks Story

An interesting account of a product so unique that mechanics often refer to it as “The Cooling System Tune-Up”.

RHIZEX, the patented ingredient in Bar’s Leaks, was first discovered in 1947 by the founder of our company, Mr. Fred Barton (1907-1975). Mr. Barton remains an inspiration to the many employees of Fre-Bar and Bar’s Products International. His basic belief in the free enterprise system, toward honesty, philanthropy and his continual dedication to hard work set an example for all those who came to know him.

Now Bar’s Leaks is factory installed in 3 out of 4 new cars made in USA by such as General Motors, Ford, and Chrysler, and Bar’s Leaks is the most widely used stop-leak and rust inhibitor in the world. Barton’s success and his rise from “rags to riches” has been featured in many national and international publications, including a cover story in the Wall Street Journal.

On June 3, 1958, the U.S.S. Nautilus, the world’s first nuclear submarine, visits Everett and Seattle.

In Seattle, crewmen dressed in civilian clothing secretly buy 140 quarts of the automotive product Bar’s Leak (originally identified as Stop Leak) to repair a leaking condenser system.

The Nautilus is enroute to the North Pole on a Top Secret mission to cross the North Pole submerged.

Bar’s Leaks – The World Champion’s Mate

When not assisting with record-breaking journeys under the North Pole, Bar’s Leaks has also helped Australian and New Zealand racing champions on the road to victory.

When World Champion Jack Brabham’s engineer rang him the night before the Ardmore Grand Prix to tell him that one of the head studs had stripped in the block, there was little choice but to cross the fingers and hope for the best.

With just hours to go before race time, there was no opportunity to remove the head. The only option was to attempt the heats in the hope that the seal around the stripped stud would hold. But it didn’t, and the engine leaked like a sieve. That, combined with a leaking fuel pump, started a fire that forced Brabham’s retirement from the heats.
