Kean,
I haven't used Zaino for quite a while (when they changed the formula a few years back, I found that for me, the new stuff would leave some smearing instead of wiping off cleanly, and that's one of my biggest pet peeves in a LSP). However, back when Z was my go-to LSP, I was mixing it with ZFX in an oral syringe to make for easy measuring, and to make sure I could dispense every last drop of product. I'd use a 4" finishing pad on my PC, and would typically use around 1/4 - 1/3 oz. for one coat (7 - 10 mL).
