Interesting read, thanks for the link.
However I think they are referring to "spray on" sealants. The sealants like Klasse/Car-Lack/Werkstadt are in a different league. They are acrylic cleaner/polishes (often called AIO -All in one) which are then topped with a second product, also a sealant but which can be layered to give a high gloss. A carnauba wax can then be put on top to give additional warmth etc.
These sealants are very populqar with owners of white/silver cars as they give an intense (sometimes quite a clinical/cold) shine hence the use of a carnauba wax to give a bit of warmth.
In your case you have a black car so you might not see the advantage of a sealant?
