Chemical Guys is a professional detailers company who happens to make products that are a high enough quality for the avid enthusiast. When we look a a lot companies that cater to the professional market we tend to see a lot of overlap in the products. Professional detailers tend to be very finicky about the products they use. If they grew up using Polish XYZ Pink, and you come up with a new polish, they likely will not want to change.
I believe 3M saw this recently. Their Perfect It 3000 Line, (particularly the compound and Ultra Fine (ultrafina) polishes were their latest (and IMO best) polishes, yet many body shops did not like them.
You end up with a vast product line to cater to your market base out of necessity. The best bet is to read the descriptions on the label, but if you have specific questions you can always pick our forum members brains.
