WHAT IS AN ABRASIVE?
A. An abrasive is a substance that wears away a surface through rubbing. There are several grades of abrasives used in compounds, cleaners, polishes or glazes. In compounds the particles are jagged, and do not flatten out when buffing, creating deep scratches. Polishes and glazes contain soft particles that flatten out when buffed, eliminating further scratching or removing existing scratches.
