It is funny how some will tout carnauba as a 'natural' wax as though it is some magically better 'organic' paint friendly product. Quite frankly, there is nothing organic or natural about a coat of paint. Zaino is the best stuff I have ever used because it bonds better, shines better (optically correct polymers) and is the easiest stuff to use one will find on the market. As far as washing it off, the only fast way to remove the coating is to use rubbing alcohol. If one uses their car wash, as do I, the polish lasts several months (garaged). Try it, you'll like it.
Oh yeah, I am the one on the teal 1200C or in the '96 LT4 vette that look as though they are both brand new. Zaino....you'll get more looks and compliments than you can imagine. (I don't sell it but I do buy it every year or so).
