I use the Pro MP quite a bit, it's my favorite penultimate product and the one I use on the S8.
It *does* contain "wax", but it's a synthetic, not a carnauba based one. Holds up for a while on its own, but not as well/long as the pink/consumer MP or WPS. Does not interfere with UPP (haven't tried other sealants over it).
Pro MP definitely has more "cut" than the pink/consumer version. I found it makes a subtle, but unmistakable difference on the S8, even when the car already looks "perfect". I use it instead of Menzerna FP, having done side-by-side comparisons with the two. But that's just a personal preference and others will go the other way.
