After searching long and hard for a carnauba topper to add to my Klasse, I finally decided to order some P21S Paste Wax from CMA.
Unfortunately, although I ordered right before Christmas, the weather here wasn't civil enough for me to get outside and throw some on, until this past weekend. My observations:
Goes on incredibly easy, comes off the same.
Shine is excellent! I had previously thrown some Meguiar's #26 on one body part, for comparison - and the P21S is clearly more reflective and deeper than the #26.
Leaves absolutely no residue, not even on the tons of black rubber trim on my ML320.
The only downside to the P21S wax was the applicator - it's incredibly small, and not very ergonomic - after one coat by hand, I was reaching for a sponge applicator I bought from Autozone to replace the supplied sponge.
I expect to get about 15-20 coats of wax out of this can, and if it's half as durable as the folks at thewaxtest.com say it is, then this is a remarkable wax.
I'll post some findings on durability after some time has elapsed. So far, durability aside - I can't be more pleased with this wax, especially on my white truck, on top of about 5-7 coats of Klasse SG.

Just a quick update on my initial post - it's just a bit more than 2 weeks later, and after exposure to some serious elements (snow, salt, dirt and rain), the P21S is holding up fairly well. I washed the car and it beaded like crazy. The hood and areas around the wheel well, which were exceptionally dirty, held up well. I decided to apply a second coat to those areas - this wax is almost like a QD - it took less than 10 minutes to hit these trouble areas again.
Funny though - between the Aquapel (Vision Blade) on my windows, and the Klasse/P21S on the paint, the car beads water like crazy.
