A direct quote:
My conclusion is based on the information I have gathered in the past year from representatives, lab technicians and chemists
from many leading car care product companies, including DuPont, the maker of Teflon. According to G.R. Ansul of DuPont's
Car Care Products Division, "The addition of a Teflon fluoropolymer resin does nothing to enhance the properties of a car wax.
We have no data that indicates the use of Teflon fluorpolymer resins is beneficial in car waxes, and we have not seen data
from other people that supports this position."
Ansul also notes that, "Unless Teflon is applied at 700 degrees F (371 degrees C), it is not a viable ingredient, and it is 100
percent useless in protecting the paint's finish."
