Prestone

Prestone is an American brand of antifreeze marketed by UCI-FRAM Group, LLC. It was originally made by Union Carbide, who spun off their consumer products in 1986 to form First Brands (see Glad). In 1994, First Brands spun off the brand to its management and Vestar Capital Partners. AlliedSignal purchased Prestone in 1997. AlliedSignal went on to purchase Honeywell and assume its name in 1999; Honeywell later sold its consumer products division, including Prestone, to Rank Group in 2011.
