Hahaha....NXT...wait till you try any really good stuff. I can go on and on about all of this! I will just say that Klasse all in one is a chemical cleaner...you can use it as a one-step process, but it is better to top it off with other things, like a carnauba wax (P21S), or a synthetic like Klasse Sealant Glaze or UPP. My biggest frustration with AIO is that it cannot be layered b/c of it's chemically abrasive properties. A true sealant has no abrasive properties so that it can be layer. I strongly recommend ANYONE, especially you Aero Blue, to try Menzerna Full Metal Jacket. I believe it was this product that caused my painter's tape to not stick onto my paint surface at the autocross. Here's a link to the product:

Pretty expensive but worth every penny I think.
