For those of you that use them or are interested two new products are now available from Zaino. Z-AIO All In One $26.95. A new wax product that replaces their Z-1. Apparently this is a wax and not a polish, has mild abrasive in it and should be used with the show car polish over it.
The other new product is Z-CS Clear Seal $29.95 seal coat for the Z-AIO.
Zaino recommends 3-4 times a year usage, you can use the Z-2 as much as you want.
I haven't used either of these yet, I'll try them in the spring. I have about 20 coats of Z-2 on my car now but I'm going to clay bar and start over when it warms up. My only complaint is these products are about $10 more than the other polish products and its hard to imagine they will out perform the existing shine. I'll let you know after I use them.
