I bought both this Chemical Guys Glossworkz Auto Wash and the Chemical Guys Extreme Bodywash + Wax at the same time, to see which one I liked more. I was half-expecting there to be no difference between the two products - kind of like on The Simpsons when the Duff, Duff Lite, and Duff Dry were all coming out of the same pipe. Anyway, I started with this wash on my dark grey Outback. The whole experience were pretty good: the wash is concentrated meaning you only need a little, good suds that lasted the duration of the wash, and results were pretty good - nice shine on the car that kept me looking back at it. So really, not a bad product at all. But then I tried the Chemical Guys Extreme Bodywash + Wax on my BMW and that just blew me away. See my review on that product's page. So is the Chemical Guys Glossworkz Auto Wash a good product? Absolutely. But because I have to vote with my dollars, given a choice, I'd pick the Chemical Guys Extreme Bodywash + Wax every time.
