I should bump this for a few reasons.
First is the fact that the clay bar process is often overlooked. Many complaints about product durability boil down to surface prep. For the enthusiasts who likes to wax their vehicle often, but have never clayed, it would be my first recommendation. Like Dutch said, follow the claying with a polish. Even if you don't have polisher, you can pick up products like scratchX or swirlx which will do a decent job of preping the surface. Autoglym Super Resin Polish will do similar, but also add some protection.
Second is that Proper Auto Care is an excellent source for detailing products. It carries similar products as Autogeek, but is much more customer oriented [in my experience with both]. Truthindetailing is their forum which is loaded with detailing information as well.
