Diminishing Abrasive
A diminishing abrasive will wear down through friction, creating smaller particles which are therefore less abrasive the more you work the product.
Therefore, when the polishing compound is first applied, the abrasive will be harsher, with some cut, so it can remove dead paint, but this level of cut can create buffer trails. However, the more you work the product the finer the abrasive becomes, turning into a finishing product which can remover polishing marks.
Most products do this to some degree, but diminishing abrasives are often advertised as being used in swirl-removers.
