unfortunately, teflon contained in auto polishes does nothing to enhance the polish or wax. dupont, the manufacturer of teflon, has even issued the following statement:

"The addition of a Teflonş flouropolymer resin does nothing to enhance the properties of a car wax. We have no data that indicates the use of Teflonş is beneficial in car waxes." -DuPont Corporation

this doesn't mean that the dealer didn't use a high quality polish on your car, it just means that the teflon in the product is probably on the buffing towel. teflon will not stick to anything unless it is heated to extremely high temperatures. that is how it is more or less "baked" on to cookware during the manufacturing process. so if you paid a lot for this teflon coating (more than a normal detail job) you were ripped off. i've used teflon polishes before i knew dupont's stance, and they provide the same shine as other polishes, but if there is really no additional enhancement, it is not worth paying any premium for. hope this helps.
