You can use ZFX+Z2 or ZAIO+Z2.... or just Z2. The Zainozealots will tell you otherwise, but it works fine, might sacrifice some durability, but not much if you use it on a truly clean surface.
I'd do ZAIO+Z2, all in one session. From what I'm hearing, you are all about the looks. The application method doesn't change the look, it changes the durability. Figure out what you like, then if it works, worry about the perfect application procedure.
