I purchased one of the NXT 2.0 kits from Wal-Mart a few weeks ago. I was in on the original NXT launch a few years back, where it seemed that NXT would be the ultimate silver bullet for virtually anything that ails your paint.
It wasn't, of course, because there really is no single product that can 'do it all'. However, 2.0 is really pretty slick -- easy to apply, and has held up well through 4 weeks of driving (that included a 2,000 mile round trip to FL from NC that started with near freezing temps and ended in FL with 82 degree temps on Dec. 26th!)
All in all, it's a good deal -- but if you need some other supplies, it's worth the trouble to track down the kit at Wal-Mart. You get the 2.0, Quick Detailer, and several other items. A good deal for $24.88!
