I recently did a full detail (over the course of many days in the garage) - good wash, clay bar, Meguiar's swirl-free polish with the Porter Cable, the Klasse all-in-one with the Porter Cable, and then a couple of coats of the Klasse sealant (by hand). I did not find the sealant to be all that tricky to use, though there were a few spots where perhaps I had applied too much, but a spritz of detailing spray let me wipe the excess right off.
I now have an excellent gloss, super-smooth feel and easy cleaning. I had done a 'test patch' with a friends pro version of the NXT Tech Wax 2.0, and could not tell any discernible difference, so I went with what I already had (the Klasse system).
P.S. My lesson learned (the hard way) - don't let any of these products touch your black top - I have two smudges on mine now, and I don't know what I'm going to do to remove the stuff ...
