One ounce to cover a Camaro is about 3 times as much as you should be using. I can easily get 3 coats out of an ounce. In my opinion, Z-6 is worth buying.

The problem might be the wiping of the wax on the black car.

When you wipe the Zaino off, especially with Z5, even if you had applied a thin coat there will be some polish residue left where you stop the towel, especially when doing the hood and roof.

I always use two towels when buffing, because wax resdiue from the first towel can stick on the paint. Just use the second towel and lightly rub over the residue spots (they look like little specks in a big group) until they are gone.

Z6 goes a long way in helping too.
