So I read and learn that the best way to apply Zaino is back and forth, as opposed to the circle type, so what do you guys do? I am hearing many say they use the machine to buff, what I am missing?

For black Z what do I need to get?

I though to get the Z5 for swirls remover, then either apply Z6 or use the Crystal guard...

Last question, I am using so far the leather chamois or drying the car, (only from water) anything wrong with that?

 

Zaino is SO easy to apply and remove using a buffer is way too much overkill, and unnecessary. Buffing generally is only useful when using an abrasive, which Zaino does not contain.

I'd get the Z-5 polish, Z-6 enhancer spray, Z-7 car wash, Z-18 clay bar and the ZFX accelerator additive.

The Z-5 will gradually fill in the swirls. If the car needs to be buffed first with an abrasive to remove the swirls, if they are that bad, do it before Zainoing.

Personally, I use an electric leaf blower and 100% made in USA cotton towels.
