I can`t lie their marketing got me too and they sell within Canada (kind of a huge plus for me). When I told a detailing buddy about the CG products I had ordered and he quickly pointed me to Autopia forums (how I got started). It wasn`t long before my CG products were replaced by superior products except for the CG dressing (extreme shine) which I still use.
CG products I`ve owned:
Mr. Pink - It smells like bubble gum and was not as good as OTC Meg`s Gold so I wasn`t impressed
Citrus Wash and Gloss - It smelled like Mt. Dew, very slick, but doesn`t clean worth a d**
Butter Wet Wax - It smells like banana, last like a week, fills nicely and looks like 845
50/50 Wax - No smell, tried it twice, I liked OTC Mothers synth-wax more
EZ Cream Glaze - Smells like Grape Drink, fills in just ok, doesn`t look great IMHO, not sure why I got a glaze.
Leather conditioner - Smells like leather, feels like hair conditioner, my leather seats are sealed so IDK why I bought this.
Extreme shine - Smells like candy, shine that lasts, restores trim, nice deep blacks, shine can be toned down with a dry buff/wipe (only keeper from CG for me)
None were "bad products" just sub-par even when compared to some OTC products. None damaged the finish of my car so no complaints here, and the smells were quite memorable (like Uber RW is).
Fortunately, my friend got my started with Klasse twins (KAIO&KSG) as my very first LSP (before my CG purchase) and eventually pointed me to these forums, the rest is history.
To the OP: if you plan to only detail your own car I recommend you try some other product lines like Meguires detailer line, Poorboy`s, WolfGang/Blackfire, and Polish Angel (they`ll impress)
