Koch Chemie Gelcoat Ultra Heavy Cut

Koch Chemie Gelcoat Ultra Heavy Cut for Severe Oxidation | Fort Myers

Gelcoat Ultra Heavy Cut is the highly abrasive machine polish for very heavily weathered, grayed, and stressed gelcoats and marine paints. When standard Heavy Cut isn’t enough on neglected Southwest Florida hulls, Ultra Heavy Cut is the aggressive prep step before stepping down the Koch gelcoat system.

Features / Why Pros Use It

• Highly abrasive cut for extreme oxidation and grayed gelcoat
• Also positioned by Koch for demanding prep on heavily stressed marine paint
• Rotary or DA with Heavy Cut Pad / short lambswool / twist wool
• Silicone-conscious restoration workflows—follow with finer gelcoat polishes

How to Use

• Shake well; apply ~5 pea-sized drops to Heavy Cut or wool pad
• Work methodically; wipe and evaluate before moving to Fine/Micro/Finish
• Do not chase perfection in one pad—step down abrasives for clarity
• Avoid hot gelcoat; protect product from frost and heat
