hi,
I normally live in the Barchetta section

, but i've got a question...
i've done a search, but couldn't find too many references/answers to teflon vs carnauba
Personally i have a preference to finish off with a carnauba based wax (mixed with elbow grease

)
But i see that more and more detailers/valetting services tend to finish off with a teflon coating... Now, i can apppreciate/believe that teflon has some better/different qualities as far as protection agains the elements is concerned then carnauba.
But there is also the finished "look" , apparently carnauba is better for a deep gloss on "dark" non-metallic colours like red , blue, green, ... and teflon should give a better "shine" on lighter metallic colours like grey, silver, ...
But apparently, once you've used teflon, it is not easy to go back to carnauba wax... (without a lot of efford)
So, there is the question... what is "better" (on a silver) Barchetta? Carnauba wax or teflon based "wax" ?
Opinions, experiences please
Thank you.
