I would't get any of those kits, I'd have no use for the terry applicators and I'd rather put together exactly what I *do* need. Sorry, I realize that's not too helpful for somebody who doesn't already know what they're after
Let's see...I'd want: Klasse AIO, Klasse SG, two-three MF covered foam applicators for the AIO, two-three foam applicators for the SG, some MFs to buff each off (get *good* ones!).
While you're shopping at AutoGeek I'd certainly get a foamgun and a BHB if you don't already have them. [Insert Accumulator's usual lecture about the wonders of these things here..] Also some WW MFs for drying after a wash and the WW MFs made just for glass work incredibly well, much better than I ever expected.
Note: when applying KSG it should go on so thin that you'll be basically unable to see it on a white car. I can *barely* see it on silver if I try very hard. Most people use literally ten times more than they need and then complain about streaking and difficult buffing. Think of it as bonding to the paint at the molecular level. A small container of KSG oughta last many years.
But I'd still give some serious thought to the Zaino, and note that I don't use it and I *do* use (and like) Klasse.
