IMHO, the specific brand of sealant, glaze and wax isn't anywhere near as important as the machine polishing and paint correction. That said, I use Adam's products, wax being Americana. I don't think there's any question that there are varying qualities of wax products, but the variation between some $10 NuFinish and some $60 Americana isn't anywhere near as great as the difference between machine polishing or not machine polishing. IMHO, if you're not machine polishing, and I'm talking about a quality machine polish not your typical $30 random orbital buffer from WalMart, then you're kidding yourself about the quality of the finish that you're going to be able to achieve.
