24-Grit / 36-Grit. Aside from grinding discs, sandpapers in the 24 to 36 range are the roughest of all grits. Typically, a grit of this intensity would be used in projects where rough edges have formed along a panel. For instance, if a car has been grazed along the side by a tree, a 24-grit piece of sandpaper could help even out the roughness.

Together, these work to grind up seeds or grains, so that the stomach can process them. Parrots do not need grit to digest food.
