Products such as 3M Perfect-It, Meguiar's Mirror Glaze, or Menzerna compounds are very popular due to their efficiency and flexibility. These compounds may be useful in fixing scratches, oxidation, and imperfections on different surfaces including automotive paint and gel coats. In addition, ensure you select the appropriate compounds for your application - some are intended for heavy cutting while others are for fine polishing. Compliance with the manufacturer's instructions is a must, and make sure you pick the right pads for the best outcome.
