is this clay good?




When the clay is rubbed against the flat surface of the car, the fine abrasives remain fully embedded in the clay and do not abrade the paint (zero abrasive force applied to surface) However, if there is a protrusion on the paint (dirt, metal particle, brake dust), the protrusion bores a small hole in the clay and the abrasives surrounding the hole are uncovered. As the clay slides across the protrusion, the embedded abrasives polish (i.e., abrade) the protrusion and either smooth it or abrade it away entirely.
One thing this tells me is that prior to using, the clay bar should be pressed firmly against the flat surface to cause the embedded abrasives not to extrude from the clay surface. Otherwise, the initial use of the clay bar would cause some abrasion of the paint before the abrasives are completely pushed into the clay.
To achieve the same result as Clay Magic or any other clay bar, one would have to mix a fine abrasive, such as a little Zaino Show Car Polish, into the clay. Because this might result in an infringement of the Clay Magic patents, I would caution against doing so.

I did a little research and discovered that Clay Magic has patents on their clay bar system which explain the theory behind the clay bar. Apparently, the clay is impregnated with abrasives (see Fig. 2 below).
