Hi, Perfecar's customer service guy here. Thanks for asking about us, we love free press.
Some of our silly products like air fresheners and window cleaners are CG products, the rest are custom made for us at a total of four different factories. It never made sense financially to make window cleaner or air fresheners (And CG doesnt even make them either, they resell those from Warner Chemical). Our top of the line wax, The Show Winner, is also a CG product (they call it 50/50, and we sell it for less). We're in the beta stages of a revision of The Show Winner, the raw materials showed up at our vegas offices to perfect a formula we think should beat it and then that will pretty much eliminate CG from our lineup.
A lot of folks have the assumption that we are a CG private label brand because their sprayers and bottles match ours, but that's just good taste using Tolco's bottles and sprayers. I wish we could manufacture our own sprayers, those little plastic parts are expensive.

Happy to answer any questions you may have... Right now almost everyone from Perfecar is at the SEMA show doing our magic including me, so my response wont be within an hour like it usually is here but it'll still be pretty quick.
Cheers,
-Ben
