David Fermani- Yeah, I'm probably one of the few clay fanatics who's never tried the CM stuff :nixweiss Guess your experience with CM Blue marring sorta undercuts their claim that it's "safe for all paints", but then it seems like every clay maker says that.
Oh, and that stuff the SpeedShine leaves behind makes it one of my fave QDs for use over waxes. I really like the stuff, just not as a clay lube.
SilverCivic- You can do pretty much claying with two bars that size, unless a) your vehicle is really contaminated, b) you drop it (not a joke, it'll happen), or c) you're as uber-paranoid about marring from contaminated clay as I am.
Cleaner-wax is usually a so-so paint cleaner mixed with a not-even-so-so wax. But OTOH, plenty of good products (1Z Metallic Polish w/Wax, the various AIO products, Meguiar's #66, and others) are either "cleaner-waxes" or the same kind of stuff, and those work very well. And lest you think I'm really down on the stuff, I've known people who kept their vehicles nice with just cleaner-waxes topped with "straight" waxes. Not "Autopian nice", but "nicest car in the company parking lot" nice.
No way to say how good that polish is until you try it :nixweiss Probably not bad though, and most likely a lot better than that.
