I first tried Zaino based on comments I read here. I think it cost me about $100 for the starter kit. It is well worth it. I have been using the same kit for about 3 years now and I still have lots of product left. I will admit that I have been getting lazy about my 'mada but it still looks very good.
For the Zaino novices, the first wash, strip, wax, etc should take about 2-3 hrs. I washed it with dawn then w/o drying it I used the clay bar to wipe the entire surface down. I use the spray mister or dip the clay in a bucket of water. Then I wash the car again. After drying it, you apply a light coat of Z2. If you have any scratches or swirls, start with the Z-5. New kits come with a tube of liquid to speed up the dry time (forgot the name). In my experience, I did not notice a difference if I skipped that step. BTW, I forgot to mention I do this in my garage. When possible, I do my car and my wife's at the same time. That way while one car is drying you can be applying another coat on the other car. This polish can be left overnight if desired. It is also great that there is no white residue (hate that). Anyway, after you put one coat of Z-5 to remove scratches/swirls, wipe off with 100% cotton towels. Then apply 1 or 2 of Z-2. I would recommend at least 2 coats for the first time. If I recall correctly, the first time I did it, I started around 9pm and finished both cars around 1am. Good Saturday night project.
Here are the results:
