KOCHCHEMIE Heavy Cut Compound 250ml — Rapid deep-scratch removal & high gloss

KOCHCHEMIE H9.02 Heavy Cut Compound is a high-performance 250ml polishing compound engineered to rapidly remove deep scratches, sanding marks up to 1200 grit, and heavy oxidation while restoring strong gloss to clear coats.

Designed by KOCHCHEMIE, the H9.02 Heavy Cut Compound blends robust abrasive action with a low-dust carrier to deliver aggressive paint correction without constant rework. In a compact 250ml format, it’s aimed at professional detailers and serious enthusiasts who need a concentrated, effective solution for correcting medium-to-severe surface defects on modern automotive clear coats.

How quickly will this compound eliminate deep scratches and sanding marks?

H9.02 is formulated for rapid material removal, capable of leveling scratches and 1,200-grit sanding traces in fewer passes than milder polishes. Your correction time decreases because the compound cuts aggressively yet remains controllable on a dual-action or rotary polisher.

• Removes sanding marks up to 1,200 grit with focused polishing cycles
• Fewer passes required compared to medium-cut polishes
• Optimised for both rotary and DA polishing techniques

Will it leave the paint surface glossy after correction?

Yes — while H9.02 is designed for strong cutting power, it also leaves a pronounced shine so that heavy correction doesn’t require immediate follow-up polishing. The formulation balances abrasive particles and lubricants to restore surface clarity and reflective depth.

• Delivers a high level of optical gloss post-correction
• Minimises holograms and swirl marks when used correctly
• Compatible with finishing polishes if a mirror finish is desired

Is this compound suitable for modern ceramic and soft clear coats?

H9.02 works on a wide range of clear coats, including softer OEM finishes and many modern ceramic-enhanced topcoats. Because it’s aggressive, test on an inconspicuous area first and adjust pad choice, speed, and pressure to match the paint hardness.

• Effective on both hard and soft clear coat systems
• Appropriate for ceramic-topped paint when applied carefully
• Recommended to perform spot testing before large-area work

How does the low-dust formula affect the polishing process?

The low-dust chemistry reduces airborne residue, keeping work areas cleaner and cutting down time spent on wiping and buffing. It also helps maintain pad performance longer, so polishing cycles remain consistent across panels.

• Produces less abrasive dust than traditional heavy-cut compounds
• Reduces pad clogging and extends pad life during jobs
• Simplifies cleanup and improves visibility while working

Who is this for: KOCHCHEMIE H9.02 Heavy Cut Compound (250ml) is targeted at professional detailers, body shop technicians, and knowledgeable car enthusiasts who need a compact, powerful correction product for tackling deep defects quickly. If you regularly remove heavy scratches or sanding marks and want a low-dust, high-gloss result without excessive follow-up steps, this compound is a practical addition to your detailing kit. Always follow safe polishing practices, choose the right pad and backing plate, and perform a spot test on sensitive or unknown finishes before full-panel correction.
