Koch Chemie Heavy Cut H9.02 is the aggressive cutting stage in the Koch Chemie polishing system. It is designed for situations where the paint has significant defects such as heavy swirls, sanding marks, oxidation, scratches or wash damage that cannot be removed with a medium polish.

The compound delivers strong correction while still finishing well for a heavy cut product. This makes it a popular choice for professional detailers who need speed, consistency and predictable results across a range of paint systems.

H9.02 should generally be followed with Koch Chemie Fine Cut F6.01 or Micro Cut M3.02 to refine the finish, especially on darker or softer paints. Pad choice has a major impact on performance, so use a heavy cut foam, microfibre or wool pad depending on the paint hardness and defect level.

Pro Tip

Start with a test spot. Heavy Cut H9.02 can remove serious defects quickly, but the best correction process is the least aggressive one that achieves the result safely.
