Amounts of Zaino To Use?

I know the advertised amounts, but I have also read some dilutions, such as w/ the spray and car wash. I was wondering what should be used for:
Z6
Z7
Z9
Z10
Z16

Thanks!

use very small amounts of Z6.

2 capfuls of Z7 is plenty for a bucket of water

for Z2/Z5, 3 coats per ounce is average (one ounce is half a mixing bottle)

Z16..depends how much gloss you want. Apply it lightly, and if you want more gloss go over again 15 minutes later.

How about the spray, I have read some talks of diluting to prevent streaking. Thanks for the info!

Mix 50/50 with distilled water.

I diluted mine 50/50 with filtered water. Still works the same, and you get twice as much for the money :)

Thanks guys.
How about the Z9/Z10??

Also, should I stick w/ the leather product on the window cowl, t-tops, dash, and inside trim, or use the Z16? Thanks!
