I don't care for it.
Let me say up front: Zaino is fairly easy to use, and produces a very, very nice shiny finish with good longevity. It is a top quality product.
I don't llike it for two reasons. First, I have a philosophical problem with their marketing claims. Second, I am an instant-gratification junkie and
I am not crazy about having to wait for long times required for it to "cure" - when other products produce results just as good and don't require that. To be fair, ZFX may address this issue.
Now, if you care, I'll voice my opinion about Zaino's marketing.
I find their claims "...nothing like the "commercial" products that everyone else sells..." and "wettest-looking", clearest, deepest, longest lasting and highest UV(40) finish protection in the industry, without abrasives or harmful silicones. Plus it is the easiest and fastest polish you will ever use. There is nothing on the market that compares to Show Car Polish products..." a bit ridiculous. This is not supported by any evidence, and
my tests demonstrated otherwise. It isn't WORSE but it clearly isn't BETTER either. I wasn't out to get Zaino in this test - I really WANTED it to live up to its claims! I'm not religious about which product I use - I will use whatever works best, no matter who it is from.
Zaino and ardent Zaino followers make 4 claims:
1) Superior shine
2) Superior longevity
3) Superior swirl filling
4) Superior dust repulsion/rejection.
I cleaned and prepped my black Porsche, followed instructions and applied their "polish-lok", 3 coats of z5 and Z2, and used Z6 - all on the right rear quarter panel. The rest of the car was prepared with standard off-the-shelf retail products. I left it on the car through several washes. I repeatedly asked car-nut friends to tell me which part of the car they thought was the shiniest/best looking, or which was different. Nobody could find a difference, and when pressed, they always chose a different section of the car.
I let the car get very dusty. There was ZERO difference between the Zaino and non-Zaino area, both in the amount of dust that appeared, and the amount that blew off when I aimed the leaf-blower at it.
My test shows that the clainmed swirl-filling properties of Z5 don't exist - at least not with the two coats I applied. And if it truly takes 5 coats (between which I have to wait, wait, wait) - what is the point? I can get RID of swirls faster than that, not just hide them.
I cannot claim to have done an exhaustive test for longevity, but I went to great lengths to try to see if it was better in the other 3 categories and concluded that, FOR ME, ON MY CAR, it was not. Again - not bad - but nothing special. There are guys that use it and love it - I say "great". Enjoy it, go for it. I just choose not to buy it.
