In May 1988 Gas Tank Renu - USA, a Michigan Co-Partnership, was officially formed for the express purpose of selling Dealerships to be licensed in the technology for the process of repairing fuel and other holding tanks. The business has grown to the point that there are now 35 Dealers in the United States and 65 when combined with the affiliated companies in Canada. The result is the largest unified system of repairing fuel tanks in North America.
