For fast cutting and a consistent finish over a long life span the P-graded aluminum oxide of this A290 coarse grit paper PSA disc roll gets the job done. This paper PSA disc roll is a good choice for blending, stripping and sanding down aluminum, composites, all woods, all carbon steels, fiberglass and soft metals, such as aluminum. The fiber reinforced, C-weight backing stays flexible while resisting tearing, the linked disc roll and pressure sensitive adhesive offer easy application and removal and the No-Fil® coating, open coat and water based stearate reduce load.
