  1. Mix at least 44 ml (1.5 oz) of cerium oxide with enough water in order to obtain a creamy consistency.
    • If the mixture is too thick, the mixture will cake on the felt pad more quickly.
    • If the mixture is too runny, more polishing time will be needed.
  2. Draw a circle around the scratches on the opposite side of the window in order to serve as a guide for locating the scratch while polishing.
  3. Cover the surrounding area with masking paper in order to catch the drippings or any splattered polish.

    Important:Β  Do not submerge the pad or allow the pad to stay in the mixture, as the bond may loosen between the pad and the metal plate.

  4. Dip the felt pad, attached to the polisher, into the mixture.
  5. Note the following suggestions while polishing the scratched area:
    • Stir the mixture as often as needed in order to maintain the creamy consistency of the compound.
    • Use moderate but steady pressure.
    • Hold the pad flat against the window.
    • Use a feathering-out motion.
    • Dip the pad into the mixture every 15 seconds in order to ensure that the wheel and the window are always wet during the polishing operation.

      A dry pad causes excessive heat to develop.

    • Keep the pad free of dirt and other foreign substances.
