Zaino - How long between coats?

[WS6Mark]

I'm just using z-2 and z-5, and I already put the polish lock on. I've let the z-2 sit overnight, and I'm about to buff it off. Can I apply another coat of either z-2 or z-5 right away? Or do I have to wait 12 hours? Zaino's site says wait 12 hours before applying another coat, but does that mean 12 hours after applying it, or 12 hours after buffing it off?

You can place another coat after you remove the other. I am not sure on the amount of time between coats usine Z-1. If you are using Z-fx you can apply up to 3 coats in a 24 hr period and only have to wait .5 hr form the time you apply the product to removing the product.
