I noticed that they leave lint as well. I've been spending HOURS on Autopia and reading the 'Guide to Detailing'. All I can say is: information overload. But, good info nonetheless.
The most significant find over there is "Microfiber". It turns out that my wife had a microfiber towel in the kitchen. I just finished using it on everything I hit with NXT (it did attract dust). I don't blame it on the NXT, though, but on my application technique ( I should have wiped immediately after the application).
The Micofiber towel worked great, so I washed the car a bit and dryed it with the Microfiber towel, worked like a chamoise (sp). I now want the 3-pack of Microfiber auto detailing towels for my birthday, along with a K&N and dyno session
