Was founded in Los Angeles, California in 1969. The original Ultraseal formula was specifically designed to seal tire punctures for the rapidly growing 4x4, dune buggy and off-road recreational vehicle market. The product received overwhelming positive response along with requests to produce additional formulas to meet the needs of conventional automobiles, trucks and equipment.
One such request came from Mickey Thompson, a well-known off-road racecar driver and an old friend of Ron and Liz Aguirre, founders of Ultraseal. Throughout his racing career, tire punctures and flats had caused major problems and cost him a race, on occasion. He encouraged Ron and Liz to expand their market into off-road racing and motocross with its large and faithful following.
