I don't think I have. the tephlon would be an ingrediant in one type of synthetic wax similar to synthetic wax with polymers. It's the same just different. Not a real fan of either. They are easy to work with but their durability generally is lacking.
I think "Pig Snot" has tephlon in it. I like to layer wax for the really bright shine, and since it has no cleaners I tried it on top of 2 coats of Tech wax, " Meguires " Great shine.
