I think the #7 defeats the purpose of Zaino. Zaino simplifies everything and makes my mobile kit very small. No need for all these different porducts when Z/2/Z5, Z6, and Z7 is all I need. I also like the fact that Zaino is durable. I just don't have the time to Z a car every week or every month. I see the cars i clean like 2-3 times a year at the most, ususally its once a year.
If you like #7, have you ever tried putting
Souveran or
Blitz over the glaze?
But hey, to each his own,
