I bought a few Chemical Guys products a while ago, mainly to satisfy my curiosity.
With the exception of VRP, I ordered products that I did not have similar in my cabinet.
The New Car Smell worked ok but did not really last.
The Mat Renew was, again, ok. It foamed up pretty good but did not change the appearance like it said it would on the bottle.
The Bare Bones was terrible. Again, it looked ok but it was like applying an oil slick to the fender wells.
The only product that can say I genuinely grab on a regular occasion is VRP. I really like this stuff as a tire dressing.
Chemical Guys have just recently been made available through a large Australian automotive chain, selling alongside the usual big box store brands. It will be interesting to see how much traction they get. Up until now, Chemical Guys products have been sold through a couple of smaller detailing supply companies here, so their brand reach has been quite small compared to how they are consumed in the USA. I also note, like a lot of things in Australia, Chemical Guys have been sold as a premium/up-market brand in the same vein as CarPro. Adams suffer the same fate also. Like for like, I can 100% say that I would take a CarPro product over an Adams or Chemical Guys for the same money.
Like others have said, Chemical Guys just offer far to many products that do the same job. Although, in small amount of deference of CG's, Meguiars also suffer from the same issue.
