I really love Zaino. Currently, I'm detailing the 330. Instead of using the Zaino claybar, I ended up using the claybar made by Griots Garage. What a difference the claybar makes.
I then used the ZPC to clean up the paint, then some Z5, since I have a dark color (ORient Blue) and topped off with some Z2. Best stuff out there.
I'm dreading the X5 though, since I never detailed it. Washing it is a PITA, so I can image detailing it will be even worse.
