Zaino is a great product to use and one that we (FUEL and myself) have had a lot of luck with as with other Autopians. I'm confused of what you mean by taking deliver of a new car. Are you getting a new car and want to know what you should do as far as detailing when you get it? I don't know how new you are to detailing or if you already plan on doing this, so I'm going to say this anyways just in case. Even if the car is new, there are still many surface contaminantes from the trip from the factory to the dealership. More than likely there's rail dust on the car and you really want to get that off, and that would mean claying your car. There's other steps you'll need to take as well, and should take anyways because again, even though the car is new, you still want to baby it.
10 layers of Zaino might be a little much. I'm not real familiar with the longevity of Zaino and if that many multiple layers (more than like 5 or 6) really makes a difference in the long run after wear and tear of mother nature. So any other Autopians, your comment would be appreciated by me and by luvthong on how many layers is sufficient. But, the main thing, I'd start out by posting the steps you plan on executing to detail your car to give you better help, especially with it being new.
