I use Zymol Carbon on the CSVT for now. . .I'm currently getting it repainted with Mercedes-Benz paint, so I might sqitch to Zaino.
I've been using Zaino on my 2003 4Runner, and to be honest, they both look pretty much the same, only zymol beads better since I have to wax at least once a month, while zaino I can do twice a YEAR. . .( I still Z2 every month, I COULD go longer, I just don't. . .)
