SHRED THROUGH OXIDATION.

Heavy Cut is our only non-diminishing-abrasive compound, built to remove heavy oxidation from gel coat. Because it does not diminish, you will always need to follow it with a refining step. It holds its cutting power through a long buffing cycle and will not dry out in direct sun, so it tears through heavy oxidation and sand scratches the fast, efficient way on boats, motorhomes, and any chalky gel-coat surface.

• Non-diminishing abrasive: Holds consistent bite from the first pass to the last instead of softening as you work, so always follow it with a refining step.
• Built for gel coat: Formulated for the severe oxidation and hardness of gel coat and fiberglass.
• Long buffing cycle: Keeps working in direct sun without flashing or drying out.
• Pads we pair with it: The Dock Boss Heavy Cut wool pad on a rotary, or a microfiber cutting pad on a dual action.
• Works best on a rotary: It compounds gel coat most efficiently on a rotary. You can use a dual action if you do not have a rotary, but it works best on a rotary.

How to Use

Rotary (primary)

1. Use the Dock Boss Heavy Cut wool pad.
2. Compound the gel coat to pull out the oxidation and scratches, keeping a controlled arm speed.

Dual action

1. Use a cutting pad and work the section. Expect it to take more effort than on a rotary.

Detailer Tips

• For the best finish, after compounding step down to Chop Top on a Deck Hand wool pad, then follow with Wake Up on the Correcting Marine Foam Pad.
• For good results, run Heavy Cut on a Dock Boss wool pad, then follow with Wake Up on a Correcting Marine Foam Pad.
• Keep your pad clean with the Pad Cleaning Spur so the cut stays even.
• Built for gel coat.
