I do love Zaino, a friend of mine got me into it so I have used it on several paints. Rossa Corsa being probably the most common to receive Zaino's system, and yes it looks great, but would still look terrible had the micromarring i.e. swirl marks, buffer trails etc etc. not been properly removed.
Zaino is well known among professional detailers for it's longevity as well. The smell of every product are fantastic, if you were use the entire lineup, and spend a day sweating over your car, you will enter your home smelling very good thanks to zaino.
For a black ferrari I would consider what I wanted out of my lsp. In my opinion it's basically longevity (synthetic) vs. overall pop and wetness (glaze carnuaba wax combo).
If you plan on being very involved in keeping up with your car, on THAT particular car I would recommend something like Meguiars #7 topped with Natty's blue for ultimate wetness. Pinnacle Souveran is a great looking wax, p21s does as well.
Megs #7 is a glaze that's very easily applied and removed by hand. It adds depth and wetness, and is a huge compliment to a nuba wax. Wipe on in straight back and forth motion, then remove with quality microfiber. Remove as soon as you're done applying to a 2 x 2 section.
Natty's blue is very easy to use, just don't make the common mistake of using too much product or you will run into difficulties. Souveran is very easy to use, work in wipe off pretty simple.
Swissvax make's great waxes I'm sure, but I have little experience with them.
The main thing to know is that even brand new vehicles (pretty much every one of them) unfortunately require machine polishing to remove surface damage induced by multiple avenues. So if I am buying a black Ferrari, and I want it to look as good as it possibly can, I'm hiring a professional who knows how to polish ppg paint. Unless of course it's single staged. What year?
