CG Website and marketing strategy is a bit unorthodox. They have many products that seem almost the same. They have other products that it's hard to get a strait answer exactly all what they do.
However, most of their stuff is very good and they seem successful so they must be doing something right. If you stick around here, you will see which products are truly exceptional.
I think some of the more popular products are: V7, Petes 53, 50/50, their shampoos (most excellent, especially Citrus Wash and Gloss), Blacklight, Stripper sent, Bare Bones, Lava, Jet Seal 109, M Seal, their towels, and XXX HARDCORE Paste Wax. For whatever reason, you don't see much to do about their traditional polishes.
Blacklight topped with V7 is a popular combo, but in true CG its hard to really define what Blacklight is. People day it has properties of a glaze, polish, LSP, or gloss enhancer. Either way, the stuff is pretty good. AG seems to have whittled the brand down a bit, carrying the more popular items.
