Abstract: A stylus device includes a lower body portion, an upper body portion, a pair of spaced shoulders, a head supported on the upper body portion between the shoulders and an outwardly extending end surface having a central portion defined by a curve wherein the central portion is rounded for controllably removing a layer of paint from a rotating painted substrate when in engagement therewith. The rounded central portion provides a relatively large amount of pressure per unit area, reduces any danger of gouging the painted substrate, and ensures a smooth, even ride on the painted substrate. The lower body portion is adapted to be removably secured to an attachment part of a scuffing head assembly. The spaced shoulders are formed at a distal end of the upper body portion and each of the spaced shoulders includes an inwardly extending edge.
