Every year Kalimex commissions an independent market research company to find out if K-Seal has maintained its number one bestselling status. Amongst many positive results, the market research consultancy reported that a massive 90% of professional motor stockists recommended K-Seal in 2011, up from 86% in 2010. Furthermore, 65% of the stockists interviewed said that when a customer asks for another brand of coolant leak repair, they recommend K-Seal instead. The survey revealed that K-Seal is the preferred and trusted permanent head gasket and coolant leak repair for professional motor mechanics too.
