### ⭐⭐⭐⭐ Works pretty well, packaging is annoying, better options out there
*by D***P on May 19, 2015*

I used this with CG Clay Luber on my Charger's Pitch Black (non-metallic) paint, and it worked pretty well. I didn't notice any scratches, but I wasn't looking very close, and the paint isn't in the best shape to begin with - lots of small scratches from poor wash technique and bad towels. Definitely works well to pull out surface contaminants! the bottom half of my car and some of the front bumper felt very, very rough to the touch. This pulled almost everything out and made it feel super smooth. Lost a star because of the packaging... Hard plastic container that the clay comes in is not air-tight, but the ziploc-style bag it comes in appears to be. That means that every time you take some out or put it back in, you have to open the bag, wiggle the plastic container out, which is a tight fit, open the plastic container, then put the clay in or take some out... doing all of this without dropping the clay itself can get a little frustrating. A slightly larger bag would make me feel a lot better about it. I guess it really shouldn't matter, as you should be able to work the clay back into usable form even if it gets a little dried out, but they definitely could have thought that through. That all being said, I'll probably move onto something like Nanoskin when this stuff runs out. Clay itself is just kind of a pain to work with.
