Shred through oxidation. If you've ever worked on a boat or motorhome with gel-coat or fiberglass material, you know that is some serious difficult paint to work with. In a situation like that, you want to use the fastest and most efficient way to get the job done.  Heavy Cut is a super strong compound that was formulated to take on the most severe paint conditions possible, especially gel-coat and fiberglass.   This compound was created with a long buffing cycle and will not dry out when buffing in direct sun. May be used with a DA Polisher or Rotary. Refer to our Compounds / Polishes Chart for a detailed comparison of our compounds and polishes.
