Zaino?.. wow.. that's old news.
If you want to spend 2 full days waxing, then yea.. I guess that's what you'd use. But - if you want to get an even better shine, and do it in half the time, then there are MANY other products to be used.
My brother owns a detailing shop, and he had very upper end cars for customers - so I know this subject like the back of my hand. He uses Klasse Sealant, about 3 layers of it, then tops it off with Pinnacle Signature Series paste wax. That will provide a deep deep wet look. There are many other steps you can take to acheive the shine you want, such as claying the car, then as a pre step, using Klasee All-In-One. It's just a matter of how many layers you want, and the type of shine you want to acheive. But Klasse and Pinnacle are one of the best combos anyone could use. Pinnacle has beat out Zaino in every comparison I've ever seen.
Meguires, Eagle One.. stuff like that.. eh. That's for the casual guy who wants to get a shine in 10 mins. In order to get a deep shine, you gotta use the right product, and know what to do with it.
If you want specific details, go to autopia.org - those forums are the best to learn how to get a show car shine.
But yea, Zaino is good.. but since then, MANY products have jumped right over it and left it in the dust.
Pinnacle is a bit pricey, but it's the Rolls Royce of waxes. Zaino is more like the Dodge's of waxes :willy:
