Yep......I'd second that notion on all NXT products being good. I want to add the fact that you have to use a cleaner, then polish before using NXT wax as the final coating. It really gives a high gloss shine for a small price.
I've been using all the NXT products since they were first introduced like a year ago; wax, wash, tire shine and vinyl protector. They really are excellent products and simple to use, not to mention smells great.
