Looking for durability, I have stepped away from carnauba and am searching for a good synthetic. NXT is great stuff. I already have 5 coats of it carefully applied at intervals on my Audi. I hear a lot of talk of layering other types over it or vice versa, but I am trying to get the best durability and a show car reflection and depth. Maybe I'll try this over Klasse AIO next, but certainly don't have Pinnacle in mind as there is not durability there.
