On my Av I have so far only used a 3M wax that I've never seen sold retail that I got from a body shop. It is a light blue liquid wax. Based on my experience with it, I like it if you can find it.
On my other vehicles in the past (as recently as last weekend) I have used Maguires which I really like. When necessary, the three part body scrub/polisher/carnauba wax works great, although it is time consuming.
I too would like to try Zaino, and probably will someday. But in the meantime if you don't want to wait, I'd probably get the Maguires. Some of the polymers work great too however (Zymol come to mind, although it is $$$)
