Hmmm...my friend just bought NXT wax. And he doesn't like it that much, simply because he says that the removal of the product is much more difficult than when removing P21S wax. I personally have not tried NXT wax, but right after my friend used the wax, he showed me the results...the car seemed brighter than with the P21S but the NXT lacked the wet look and depth of shine provided by the P21S.
