I haven't used Zaino in about 7 years, but when I did, I loved the stuff. Back then I used the older Z-2 formulation, I think. When applied to bright silver followed by the Z-6 spray, it looked awesome!
But now I see that Z-5 Pro is available, and Zaino's website state that Z-5 Pro may be better suited for darker vehicles, especially those with swirl marks (which I don't have) or fine scratches (yeah, I have some of those). I would consider WRB a darker color. However, some users of Z-5 Pro are layering it will Z-2. Why not just stay with Z-5 and call it a day?
So many questions, I know. Basically looking to use one polish (either Z-2 Pro or Z-5 Pro) in conjunction with ZFX and Z-6. I'd also maybe go Z-AIO, but I understand that Zaino actually adheres well to Klasse AIO, which I own and need to use up!
Any help and experience will be appreciated. Thanks!
