I've been a zaino user for a couple years now. My twice a year detailing regimen is as follows:
1. Clay with Mothers. Can't remember the exact name but it's the box that comes with a clay bar, a bottle of quick detailer/lubricant, and cleaner wax that you can buy at autozone for $17. I don't use the cleaner wax though.
2. Klasse AIO. Incredibly easy to use. Just apply and buff off. No drying time needed. Some people say it's hard to buff off but that's only if you let it sit for too long. I go one body panel at a time so the AIO isn't on the paint for more than a few minutes.
3. 2 or 3 layers of Z5 or Z2. Zaino has gotten a lot easier to use with the introduction of the ZFX additive. Just apply, wait 30 mintues to dry, and buff off. You can do up to 3 coats in one day. I don't get why some people are afraid of it. Maybe the instuctions on zaino's website make it sound more difficult than it actually is.
The main draw of zaino for me is its durability. I've gone 8 months between applications with just an occasional wipedown with z6 and water beaded just as well as the day I applied it.
I'm also a fan of zaino's leather cleaner and conditioners, tire shine, and car wash soap.
here's a picture of my car from last winter:
