June 3, 1986 – The beginning of the Slip-N-Grip® seat cover. At the time, this was a major breakthrough in the plastics industry. The plastics material was developed by Paul Keiswetter, in conjunction with Ford Motor Co. and was tested locally at Tallburg Chevrolet-Olds in Petoskey. At first this two-ply plastic film was used by car dealers and repair shows to protect the car’s interior while the mechanic worked. It now includes the exterior of the car as well with full covers.

Slip-N-Grip® is a division of Petoskey Plastics serving the automotive aftermarket with a variety of vehicle protection products that help exceed customer expectations and keep them coming back. Today, the Slip-N-Grip® line includes plastic seat covers, paper and plastic floor mats, steering wheel covers, tire bags, dispensing systems and dozens more products for vehicle service operations.
