Put me in the polish/carnuba camp as well. I've used Zaino in the past and it is certainly nice stuff but just wasn't for me. Currently Ive been using Klasse All-In-One followed by either P21S or Pinnacle Souveran. (Switched to P21S - The Souveran is just too damn expensive).

 

Here is a Black 05 w/ Zaino Z2 3 coats !

 

My Diamond Graphite G doesn't photograph as well as my last car with a couple coats of Zaino.
