Their products are a little pricey, but they have a 100% satisfaction gaurantee (which I've tested), and they work as described. Some of the best detailing products I've ever used and I've used a bunch. These guys think of everything.
I use their clay bar with my random orbital, their machine polish 2 and 3, and their paint sealant once a year on all my vehicles to keep them looking like new.
