KOCHCHEMIE Heavy Cut Compound 1 L — aggressive paint correction, low-dust gloss

KOCHCHEMIE H9.02 Heavy Cut Compound (1 L) is a high-performance paint correction compound engineered to remove deep scratches, oxidation and sanding marks up to 1,200 grit while restoring strong gloss.

Designed for professional detailers and serious DIYers, this heavy-cut polish combines aggressive abrasion with a low-dust, long-working formulation so you can correct paint defects without excessive residue. The product suits a wide range of modern clearcoats — from softer legacy systems to harder, contemporary finishes — and is formulated to deliver both material removal and a refined sheen in fewer passes.

How does H9.02 remove deep scratches and sanding marks?

H9.02 uses a coarse-cutting formula that abrades and levels the paint surface efficiently, making it possible to eliminate visible defects left by grit up to 1,200. The compound balances cutting power with lubricity so the abrasive action remains controlled and predictable.

• Effective against sanding marks through 1,200 grit
• Aggressive but controlled material removal
• Designed for rotary and orbital polishing systems

Will this product give a good finish or will I need a separate polish?

H9.02 delivers an impressive level of gloss while performing heavy correction, but for an ultra-refined mirror finish you can follow with a finishing polish. Many technicians achieve a high-shine result in fewer steps thanks to its balance of cut and gloss.

• Superior gloss retention compared with typical heavy compounds
• Works well as a stand-alone step for many defects
• Compatible with follow-up fine polishes for showroom gloss

Is this safe on modern paint systems and ceramic clearcoats?

H9.02 is formulated to be effective on a wide range of clear coats, including both softer older systems and harder modern or ceramic clear coats. As with any abrasive correction, test in an inconspicuous area and use appropriate pads and speeds to avoid overcutting thin paint.

• Suitable for soft and hard clear coats
• Compatible with contemporary ceramic-finish paints
• Recommended: test spot and choose pad/hybrid-speed accordingly

How does the low-dust formula benefit a detailing workflow?

The low-dust characteristic reduces airborne residue and pad clogging so you spend less time cleaning surfaces and more time polishing. That means longer uninterrupted polishing cycles, clearer defect visibility and faster overall correction.

• Produces less dust than standard heavy compounds
• Reduces pad glazing and frequent cleaning needs
• Improves visibility of remaining defects during correction

Who is this for? KOCHCHEMIE H9.02 Heavy Cut Compound (1 L) is aimed at professional detail shops, body shops and ambitious enthusiasts who need rapid, reliable removal of deep scratches and sanding marks while preserving gloss. If you perform regular paint correction or restore vehicles with heavy surface damage, this concentrated 1-liter option provides pro-grade performance and enough volume for multiple jobs.
