6 COATS here. Nowadays, if I use ZFX I always mix a little LESS than 1/2 oz and I get 3 coats and still have a little leftover, so I guess I can do more than 6 coats out of 1 FULL oz.
When I first started using Z, I was getting 3 coats out of 1OZ (
Click to see my very FIRST Autopia Post about this .) Then 2 coats out of 1/2oz. Then 3 coats out of < 1/2oz. I guess the more you play with it, the thinner you go.
This is the reason why I try not to use ZFX if I only intend to do 1 coat. I really don't know how to calculate exactly how many oz of Z and how many drops of ZFX to mix for just 1 coat... Always end up wasting and throwing the the unused portion away.
I really wouldn't worry too much if you are not getting as many coats out of an ounce. Once I described to Sal how I apply Z and how less and thin I was doing, and he told me I could apply
a little more if I want.
