Wow, what a debate here. Personally I have *yet* to try Zaino and the Meguiars Gold Glass I used before last winter is still holding up so I'm happy with that. Once I use up my current supply I'll be ordering some Zaino to see for myself how good it is.
The problem with arguing something like wax on an internet forum is that all you have for compairo' are pics and opinions. Neither of which make much of a difference in the end. As the saying goes 'A picture is worth a thousand words'...but in the case of arguing wax/polishs' all of those 'words' are shiney. There is a lot more involved in determining the 'better wax'. Shine is completely objective...long life, ease of application, low odor, and cost are the things that matter when you get down to figuring the best wax.
