Wax+Teflon. Is it really so good?

[RobX5]

Hi Dear fellow X5 Owners,
just recently came across an idea of polishing my lovely black horse with teflon. had a look through e-bay, googled 'teflon car polish' and actually not much can be found out there. Does it mean this is some new kind of stuff? Teflon has been invented in 1940's so I'm just thinking someone should have tried it on the paintwork by now... I generally like the idea of it- just polish your car once and then for at least a couple of months don't have to bother about redoing it. Sounds tempting, ha? Perhaps anybody has any experience on that?
