Don't use your machine for Zaino it's not at all recommended. If you do I'd just use a buffing pad. Not the foam ones but the feathery type ones or even MF pads. You only need a machine if your surface needs to be polished, does it have swirls? Then you need a couple of polishes, my favorite Menzerna IP and FPII. Then just wash your car after and put your Zaino on. If your car isn't that bad just try Menzerna FPII, I say this because I know your dying to try your machine. Just have a spray bottle handy with this product, spray the pad before you apply the FPII. Use a finishing Pad, get a white pad if you buy IP, and an orange if your paint has swirls. If your paint is good but you still just want to use your machine consider a paint cleaner like p21s or klasse AIO, both can go under Zaino and will make it look very nice, use a finishing pad. You might want to wash car after, or at minimun spray with water or Z6 and good MF towel.
ZFX- You need ZFX it will make the product more durable among other things. Not only that but it makes application easier than any other sealant. When you put ZFX and Z2 in the bottle, it makes the product spread as easy as water. You can put tiny drops all over your car and just take your applicator and spread the dots. If you feel like it once you have your ZFX/Z2 treated surface, you can put z2 on the surface and even leave it on overnight, then buff it off with your machine and a MF pad. The whole reason Zaino has the reputation it has is because of the ZFX. This instant cure is just as revolutionary as when they developed synthetic sealants to out perform the nuba waxes. I have been waiting for any other company to develop something like ZFX but to my knowledge there is nothing out there, so why omit something like that? One bottle of ZFX lasts for about two bottles of any Zaino polish and makes the polish last longer because you can spread it thinner.
