Koch-Chemie Heavy Cut H9.02 — Coarse Polishing Compound

Koch-Chemie Heavy Cut H9.02 — Coarse Machine Polishing Compound

Koch-Chemie Heavy Cut H9.02 is an innovative, silicone-free coarse machine compound engineered for the rapid rectification of heavily weathered automotive clearcoats, deep scratches, acid etching, and sanding marks up to P1200 grit. Developed with specialized homogeneous abrasive aluminum oxide micro-particles, H9.02 achieves an exceptionally high level of cut with an outstanding gloss finish, operating virtually dust-free without sticking or splattering.

Approved and recommended by global automotive OEMs (including Daimler, BMW, and Audi), H9.02 is optimized for both scratch-resistant ceramic clearcoats and conventional factory paints. It contains zero fillers, silicone oils, or waxes, ensuring genuine defect removal that will not wash away or revert.

Step-by-Step Professional Application Protocol

1. Thoroughly wash, decontaminate (using Koch-Chemie Reactive Rust Remover and clay), and dry the vehicle paintwork.
2. Shake the Heavy Cut H9.02 bottle thoroughly before use.
3. Prime a clean Koch-Chemie Heavy Cut Pad (Red) or Lambswool Pad with 4–5 pea-sized drops of compound.
4. Place the pad flat against the paintwork and spread the polish evenly across a working area of approximately 40 x 40 cm at low speed (rotary: ~800 RPM; DA: speed 2).
5. Increase machine speed to medium-high (rotary: 1200–1500 RPM; DA: speed 4–5) and guide the polisher in overlapping cross-hatch passes using moderate downward pressure.
6. Continue polishing until the compound turns into a clear, oily film indicating abrasive breakdown.
7. Reduce downward pressure for the final pass to refine the finish.
8. Wipe off residual compound gently using a clean, borderless microfibre buffing cloth (Koch-Chemie Polish & Sealing Towel) inspected with an inspection lamp.
9. Follow with Koch-Chemie Micro Cut M3.02 to eliminate micro-holograms and achieve maximum depth and mirror gloss.

Pro Detailing Tips, Do's & Don'ts

• DO: Clean the polishing pad regularly using compressed air or a pad conditioning brush between sections.
• DO: Follow up with Koch-Chemie Silicon- & Wachsentferner to inspect true paint condition prior to coating.
• DON'T: Do not overload the pad with excessive product; excess compound causes pad clogging and reduced cut.
• DON'T: Do not apply on hot surfaces or in direct sunlight.
