i'm no guru but
clay magic from autozone is a good bar. and easily picked up. avoid the mother's clay. when you get the bar. cut it into four pieces. use the provided lube or left over soapy water from the wash to lube. run the piece of clay over the surface til you feel no more grit (should glide smooth) be sure to keep the area well lubricated. periodically rework the clay to push the dirty parts into the clay and have a fresh surface. if you drop the clay, if you can cut off the part that touched the ground good, but as a rule anything that touched the ground shouldnt touch your car again. so clay on ground = clay in trash. once the clay runs smooth, move on to the next spot. if you are using a QD for lube, then buff off as you go. if you are using the soapy water, then wash again. personally no matter what i use to lube i rewash.
as for zaino. the key is THIN coats. THIN THIN THIN. the first time is always hard. but it gets easier and easier. and z6, the QD, apply in small sections and buff well. it seems like it comes off hard, but if you only apply it to a small section and buff quickly, it's great. also z6 in the hot sun isnt good. you have to buff super quick in that case. 31st330i apparently talked to sal z and found that z2 and z5 are identical with z5 having fillers for swirls. although the site does say z2 is "optically" perfect or wahtever.
by the way, zaino has no true paint prep stage.
so if i were you and were going to do the whole deal, i'd dawn wash, clay, wash with quality wash, polish of some sort (p21s gepc, ppcl) or any other surface prep (scratch, swirl removal), then wash again to get rid of any oils left, then start the zaino
