This stuff sounds(and looks) like good sh!t. Is it applied with a power buffer or by hand? How many different steps? Clay Bar first then start with the Zaino?
by hand...one directional, no swirling...just front to back strokes....clay bar may be good first ,dep on the current shape of 'trash' on the paint...I didnt as my first Zaino was 2 yrs after new paint...
