I finally decided to top NXT with a carnauba and figured I'd try #16 Professional Paste Wax first. I haven't used #16 in a while and forgot just how nice a look it has. Anyway, on top of NXT, #16 added noticable wetness to the paint. It really is a nice look. I've got it on my car and a metallic black BMW 745 (took pics of it) that I should have posted in the next few days.
If you are looking for something to top NXT with and have a container of #16, it is definitely worth trying.
