Zaino - How much you use for 3 coats?

I am curious as to HOW MUCH of the 2oz. bottle do you use to do your entire 3 coats? Using ZFX. and either Z2/Z5

NOTE: This is ONLY being used on the Paint, not the windows

1. What year, model Car?

2. How much do you fill the 2oz bottle? (full, 3/4, 1/2, 1/4?)

3. How much is left in your 2oz. bottle once you've done your 3 entire coats? (

Thanks

Car in sig.

Half full

None after 3 coats...paint, wheels, and glass.
