Found this interesting because I've heard so much about Zaino so I was looking for some reviews. Found this well thought out comparison between Zaino and Zymol as well as Meguiars. I use Meguiars but I've seen people's pics with the Zaino and they look fabulous. Morale of this story don't pay $144 for NSX wax.
Anyway, here's the link.
