KOCHCHEMIE H9.02 Heavy Cut Compound 1L — High Cutting Power, Low‑Dust Formula for Deep Scratch Removal

KOCHCHEMIE H9.02 Heavy Cut Compound is a high-aggression polishing paste that removes deep scratches, oxidation and sanding marks up to 1,200 grit while restoring strong gloss on modern clear coats.

Designed for professional detailers and serious DIYers, this 1‑liter heavy cut compound combines powerful abrasion with a low‑dust, non‑drying formula so you can correct paint defects efficiently without sacrificing finish quality. It handles a wide range of clear coats — from softer older lacquers to hard, contemporary ceramic‑enhanced finishes — and was engineered to deliver repeatable, German‑style results that speed up correction jobs and reduce follow‑up polishing time.

How quickly will H9.02 remove deep scratches and sanding marks?

H9.02 is formulated for aggressive material removal, capable of erasing defects produced by sanding up to 1,200 grit and many deeper scratches in far fewer passes than mild polishes. Correction speed depends on pad choice, machine speed and the depth of the defect, but you can expect visible improvement after the first pass.

• Effective on scratches and sanding marks up to 1,200 grit
• High cutting power reduces the number of polishing steps
• Works with rotary and dual‑action polishers using appropriate pads

Will it leave a high gloss, or is it only for cutting?

Although H9.02 emphasizes cutting performance, it also restores strong gloss so surfaces look polished rather than dulled after correction. Its abrasive system is balanced to remove defects while leaving a finish that often needs only light finishing polish to achieve showroom shine.

• Superior cut plus notable gloss retention in one step
• Compatible with follow‑up finishing polishes to refine shine
• Minimizes holograms and fine marring when used correctly

How easy is the product to use — does it create dust or dry out quickly?

H9.02 features a low‑dust, non‑drying formulation that stays workable during longer polishing passes and reduces airborne residue compared with traditional heavy abrasives. That improves visibility of results and keeps pads cleaner for extended use.

• Low dust formula for cleaner working conditions
• Does not cake or dry prematurely on pads and paint
• Designed for continuous polishing without frequent pad changes

Is this compound safe on modern clear coats and ceramic finishes?

Yes — H9.02 has been engineered to be effective across a broad range of modern clear coats, including harder, ceramic‑enhanced systems. Follow proper test spots and correction technique to avoid excessive material removal on thin or soft clear coats.

• Works on soft and hard clear coats, including ceramic‑treated paints
• Recommended to test in an inconspicuous area before full‑panel correction
• Use appropriate pad aggressiveness and machine settings for best results
