Big Zaino fan here as well but I went for Opti-Guard for the sealant on the Z. Once applied it is on for the life of the car, no more sealing waxing or anything required. Nothing can bond to it, bugs water spots you name it wipe right off with almost no effort at all.
All you should ever need to do is top it off with some detail spray of your choice. This is where the Zaino Z8 would come in to provide the bling over the top of the opti-guard.
I also have Xpel on the nose and gill areas of the car because there is no sealant or wax type product that will prevent rock chips.
So far extremely happy with my choices
