Many auto care product manufacturers advertise Teflon waxes, sealants, and polishes as lasting for unrealistic lengths of time, protecting your vehicle's finish for anywhere from one to five years or longer. The general public often believes this false claim, reasoning that a frying pan coating would certainly protect their vehicle's paint. However, DuPont (the maker of Teflon) issued a bulletin to dealers stating that this floral polymer resin must be baked onto a surface with a high heat process or chemically etched before adhering to any surface. Rarely adhering to a vehicle's finish, Teflon has a dull, flat appearance. If DuPont meant Teflon to be used as a wax, they would have a patent on it and would be the only company selling Teflon wax or sealant. But many wax manufacturers purchase Teflon resin from DuPont in one of its hundreds of forms. They then put the smallest amount possible into a container of wax or sealant to legally call it a Teflon sealant. Since Teflon is ineffective as a finish protector, these advertisements simply are gimmicks .
