Koch-Chemie Heavy Cut Coarse Polishing Compound v2 - Fast Deep-Cut

In this review the Koch-Chemie Heavy Cut Coarse Polishing Compound v2 is evaluated as a specialist machine polish for restorers and professional detailers who need aggressive cut without silicone oils. The bottom line: it removes heavy weathering, deep scratches and sanding traces up to 1,200 grain while still producing a very good gloss, so it is best for technicians who demand fast material removal with predictable finish. For hobbyists it can be effective but its strength and cost make it a better fit for experienced users.

Key Features

• High cut capability: The formula provides extremely strong material removal to eliminate deep scratches and heavy weathering quickly.
• Silicone-oil-free: Being free of silicone oil helps avoid residue issues and makes it safe for follow-up coatings and detailing steps.
• Low dust and non-sticking: It polishes for prolonged periods with minimal dust generation and without sticking to pads, improving workflow.
• Versatile on paint types: The compound is suitable for both soft paints and modern scratch-proof paints, reducing the need for multiple products.
• Removes sanding traces: It effectively removes sanding marks and paint mists from work up to 1,200 grain, saving time in rework.
• Professional pedigree: From a company with decades of workshop and vehicle care experience, formulated for expert use.

Who It's For

The compound is aimed at professional detailers, body shop technicians and experienced enthusiasts who need a powerful coarse polish for heavy defects and fast rework. It is particularly useful when removing deep scratches, heavy oxidation or sanding marks where a high cut rate is required.

Less experienced users or owners looking for a finishing polish should look elsewhere, since the product is aggressive and intended for machine use; minor swirls and light defects are better handled with a finisher polish.
