Buck22:
You asked the same question I had about which One-Step or All-In-One product to use. There seems to be some confusion between a Cleaner Wax and an All-In-One and the grey-area about their overlapping cleaning and protecting abilities. I think the general consensus is, in layman`s terms, is that Cleaner Waxes use chemical, while All-in-One`s use abrasives for cleaning and minor polishing. BUT that is not the case with Klasse All-In-One, which uses chemicals for its cleaners, hence, the confusion with the names.
I will defer to the thread I started on this very topic, and you can make your own value judgments about which AIO/Cleaner products you may choose to use:

I will say this: I use Turtle Wax`s Hybrid Solutions Ceramic Polish and Wax first , followed by their Ceramic Spray Coating because it was cheap (like me!) and available over-the-counter at Walmart. It`s an `inexpensive" one-two "modern" way to polish and protect a vehicle, especially if you have a Porter-Cable Dual Action Orbital buffing machine or Griot`s Garage G9 buffer to use, rather than trying to do the polishing step by hand.
That said, I think many Autopians would suggest "stepping up" to Blackfire`s One-Step followed by their SiO2 Sealant Spray as THE way to go if you want a "modern" one-two way to polish and protect in an easy-to-use product format.
One caveat about spray coatings: they are a "fake" coating compared to a true coating and while are touted as "coat like a Pro", they offer neither the protection or longevity of a true coating. In this case, you get what you pay for and these spray coating are grossly over-hyped and marketed by their manufacturers. But, as stated, they are "inexpensive" and easy-to-use, hence, their appeal for the hobbyist or do-it-yourselfer detailer/car-care person
