Very smooth, prefer this over the Clay Magic Blue, because it is more gentle.

great clay it really pulls the contaminants out of the paint

I'm struggling to find a huge difference between this product and the more traditional "blue" clay from Clay Magic. There is an obvious softer, more pliable feel. There is the benefit of being able to see contaminants that are pulled from the paint more easily due to the almost white color. But I'm not sure about the "Polymer" addition into the name. It's suppose to give a wax like finish after use, which is confusing. The blue clay does the same thing in my book. If nothing else, I'll say that it's slightly less aggressive than the blue, so more confidently used on softer paints.
