You don't hear or read too much about the Yellow Cream Wax, but I'd equate it to more of a glaze than a wax since it contains polishing oils but no chemical or abrasive cleaners. It's not a must have from ClearKote, but it does add some depth and slickness.
The CK products I definitely reccomend:
VM: a great glaze that has very mild abrasives to clean things up a bit. Use your PC and apply it to everything: paint, rubber (trim), and glass.
RMG: another great glaze with some chemical cleaners and a bit more depth than VM. Some like to mix the VM and RMG but I find them such a pleasure to use that I just top VM with RMG.
CMW: one of the better and more affordable waxes on the market. It has great depth and wetness that comes close to paste Souveran.
Quik Shine (QS): a great QD that even seems to work better than Rain-X on a windshield.
A couple of years ago I did the whole CK treatment to my street rod: VM, RMG, YCW, and CMW. A few days later we were at a hotel parking lot for a car show and my friends wife, who was sitting between our cars, mentioned that my car looked wet. I've never heard her describe a car that way before or since.
