My Z-2 and Z-5 have been sitting on the shelf in my garage for a few years, so I wrote to inquire what the shelf life was. From my own experience, the ZFX solidified after a few years. Here is Sal's anwer:

Every product made has a usable shelf life...

I found that room temperature gave the best longevity for Zaino products... so that's what I prefer... The optical additives I use do not like extreme heat or cold. It will decrease there gloss enhancing properties.

When stored in a cool dry place. Avoiding extreme heat or cold. Shelf Life is as follows.

Z-1 For optimum results use before 3 years.
Z-2 For optimum results use before 3 years.
Z-5 For optimum results use before 3 years.
Z-6 5 years +
Z-7 5 years +
Z-8 5 years +
Z-9 5 years +
Z-10 For optimum results use before 2 years.
Z-12 For optimum results use before 2 years.
Z-14 For optimum results use before 2 years.
Z-16 3 to 5 years
Z-18 5 years +
Z-PC For optimum results use before 3 years.
ZFX For optimum results keep tightly capped and use before 18 months.
Z-AIO For optimum results use before 3 years.
Z-CS 5 years +

Thank You,
