Quiet whispers of 'solvents', 'abrasives' and 'oils'. They think they can take the MSDS sheet and know exactly what is in NXT...and of course, if it isn't as 'pure' as Zaino, they have to knock it immediately. I can't figure out people like that. It's only wax, dammit. If you don't like it, don't use it, but don't subtly tear it down and then say you'll stick with Zaino. NXT has only been in our hands for a few weeks, it is way to early to make any firm conclusions one way or the other. BTW, so far, it is a pretty decent product. Appearance-wise, it seems to be a good comprimise between the super reflectivity of the best sealants and the deep wet look of a tradition carnauba. Pretty much has the look of a sealant with a carnauba topper, IMO. I haven't had it long enough to know how durable it is though.
