Abstract
Abstract A compound containing a tall oil fatty acid, oleic diethanol amide, aluminum oxide abrasive material, and organo-treated bentonite provides a polish for metals, such as aluminum, having a uniform viscosity and the abrasive particles uniformly dispersed throughout the carrier. Water may be added to form a scratch removing compound. Mineral spirits may be substituted for the fatty acid in the scratch remover to form a prepolish compound.
