Did the Zaino deal. Works great. Read somewhere to re-appy twice a year for average street vehicle, but can't seem to find it again. My question is do I use the Z1 again when I put on another coat of Z2 in the future?

No. You only need to use Z1 about every 6 months or so. I use Z1 after about every 4 coats of Z2.

Actually the Z1 is great at removing stuff the wash didn't.
