Zaino is great stuff...I started using it on my MB AMG four years ago and swear by it. I have yet to give the new 987S the treatment but will as soon as possible.
I also use Klasse All-In-One on my Ford Expedition with great results. Given the Expy is so big I didn't want to worry about multiple Zaino applications. The Klasse is very good for a quick one coat application.
