Unlike some previously used waxes, Zain is recommended for application to plastic molding and lenses. What about the moonroof on your "X?" Do you Zaino it?
Yes, Zaino works great on glass, both Z2/Z5 and Z6. I just use it on the outside glass, not on the inside glass. It is not quite as effective as RainX, for example, but is far, far easier to apply and buff off.
