Try the NXT I used it for the first time yesterday, prior to that i've used zaino. NXT ROCKS i love it! car has such a high high high gloss, i dawn washed the car then clay bar, then washed it again, then used NXT. I'll post of up some pic's later tonight when i get home.
i use both! a coat of Klasse followed by a coat of NXT. The Klasse will thoroughly clean/polish/protect the paint. the NXT on top makes it look sharp. both products very user friendly. Ive used meguiars gold class and #26 extensively. The NXT in my opinion is better.
