After I apply Z1 and Z5 at the first time.
what is the next step if my Z gets dirty??
Apply Z6 first and then wash with Z7 and dry my car??
or wash with Z7 and apply Z6 and then dry??
and then should I apply Z5 without applying Z1??
and Do I have to wait 4 to 12 hours to dry it as the first time???
and then it's done????
The instructions says just use Z1 twice in a year
So I don't have to use Z1 Right??
I am little confused
Thanks!!!!

 

When the car gets dirty, wash it with the Z-7, after drying follow up with the Z-6.

If the car is just dusty, use a California Duster and then Z-6 it.

The Z-1 (or ZFX) is ONLY needed the first time, twice a year or every 10 coats. You can use it more often if you want, but it isn't necessary. So NO, you don't have to use the Z-1 for a while.

If it is taking 4-12 hours to dry you are using WAY too much. You should be able to do a single coat with LESS than 1/2 ounce. Using any more than that is simply wasting product. Humidity will affect drying time though.

Without using the ZFX, you have to let the previous layer cure for at least 6 hours above 70* or up to 24 hours below 70*.
