Not sure what scratchies are, but clay bar does not remove scratches. It removes debris on the surface of the paint. In fact, clay bar can create scratches if not used properly, i.e. not enough lube or too much pressure). I have heard of alternatives to clay bar in the form of a pad or glove. But scratch removal is not the purpose.
I couln't see how any claybar type product could remove scratches in clearcoat or paint either. But I used to use "heavy" paste wax, and, with that on the car, it is possible to get small scratches in the wax only. I think a claybar-type product will remove those, because claybar removes the top of the wax layer. But that is all.
