Frequently asked questions
Which Koch Chemie gelcoat compound is for heavy oxidation?
Ultra Heavy Cut is for very heavily weathered, grayed gelcoat and marine paint; Heavy Cut is for heavily weathered, chalked gelcoat. Both run rotary or DA with a Heavy Cut Pad, short lambswool or twist wool, then step down to Fine Cut or Gelcoat Finish.
Fine Cut, Micro Cut or Gelcoat Finish: what's the difference?
Fine Cut is for medium-weathered gelcoat and preps for a high-gloss polish (Fine Cut Pad). Micro Cut removes polishing haze, holograms and fine scratches on lightly weathered gelcoat (hard Micro Cut Pad on a DA). Gelcoat Finish refines lightly weathered gelcoat, as the step after Fine Cut or a light one-pass.
Does Koch Chemie Marine have a one-step gelcoat polish?
Yes. Gelcoat One Cut is a 1-step machine polish for all gelcoat and boat paint colors that removes haze, holograms and scratches with a sealing effect, run on a DA with the hard Micro Cut Pad. Keep it off unpainted plastics and rubber. Micro Cut & Finish refines and seals in one pad.
Acid or alkaline Hull PreCleaner?
Hull PreCleaner Alkaline is phosphate-free and breaks traffic film and organic soils. Hull PreCleaner Acid is for salt and mineral fouling before Boat Wash or polishing. Both are highly concentrated pre-washes for gelcoat, paint and plastics on decks and hulls.
How is this different from the Koch Chemie collection?
Koch Chemie Marine is the boat-specific line (gelcoat compounds, hull pre-cleaners, Boat Wash, marine sealant and interior care). The Koch Chemie collection carries the broader auto + marine catalog, including the H9.02 / F6.01 / M3.02 paint compounds, snow foams and clay.
