Serious Correction
Koch-Chemie Heavy Cut H9.02 is built for the jobs that test your patience - heavily weathered clear coats, deep scratches, and paint that has been neglected for years. The formula cuts fast under machine, so you spend less time on each panel and get better results.
Why H9.02
Four reasons professionals reach for H9.02 first
Cuts through deep scratches and heavy oxidation in fewer passes than a standard compound.
Koch-Chemie engineering delivers consistent abrasive performance on heavily weathered clear coats.
Leaves a surface that steps down cleanly to a finishing polish without excessive micro-marring.
Engineered specifically for rotary and dual-action polishers, not hand application.
H9.02 vs The Alternative
Not all cutting compounds are built for the same level of defect. Here is how H9.02 stacks up against a typical mid-range compound you might reach for first.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Removes deep scratches in one pass | Yes | No |
| Effective on heavily weathered paintwork | Yes | No |
| Safe on clear-coat finishes | Yes | Yes |
| Requires machine application | Yes | Yes |
| Needs a finishing stage after correction | Yes | Yes |
| Professional / body-shop grade cut | Yes | No |
Professional Results
H9.02 handles the hardest part of a full correction detail, leaving you with a defect-free surface ready for finishing and protection. It is a staple in body shops and detailing studios for exactly this reason - reliable, fast, and consistent in its cut.
Reviews
Had a white sedan with years of neglect on it - oxidation, scratches, the lot. H9.02 cleared everything in a single correction pass on the DA. Stepped down to a finishing polish after and the paint looked brand new.
Deep scratch on the door had me worried. Two passes with H9.02 on a cutting pad and it was gone. Strong product.
Proper cut, no question. You do need to follow it with a finisher or the micro-marring is noticeable, but that is expected at this level of abrasion. Results on heavily oxidised paint are excellent.
Three-stage correction job on a fleet bakkie, H9.02 did the heavy lifting. Faster removal than the compound I was using before.
Tried it on a rotary first, then on a forced DA. Both worked well. The rotary gave more bite on the worst scratches. Finish after stepping down to a fine polish was excellent.
Arrived well packaged and the product itself is the real deal. A bit of patience needed to work it properly but the correction on weathered clear coat is exactly what I needed.
Sanding marks from a 1500 grit wet sand came out cleanly. Needed two passes but the results were clean and consistent across the panel.
Not the product for someone looking for a quick light polish. It is exactly what it says - heavy cut, serious correction. If your paint needs it, this will sort it.
Koch-Chemie quality throughout. The cut is aggressive enough to handle neglected paint but it does not feel uncontrolled under the machine. Confident product.
Questions
H9.02 is designed for machine application. It works well on both rotary and forced dual-action polishers. A rotary will maximise cutting power on the most severe defects, while a forced DA gives you more control on panels with complex curves.
Pair H9.02 with a firm cutting or heavy-cut foam pad, or a microfibre cutting pad for maximum aggression. Because this is a heavy-cut product, avoid soft finishing pads - they will not generate the heat and friction needed to work the abrasives effectively.
Yes. H9.02 is formulated for clear-coat and single-stage paintwork. Because it is a heavy-cut product, work carefully on thin or soft lacquers - check your paint thickness before starting, and do not over-work any single area.
Yes. The heavy-cut formula is capable of removing sanding marks left by wet-sanding, as well as deep scratches and oxidation from heavily weathered finishes. Start with a cutting pad and assess the results before moving to a finer finishing stage.
After heavy correction with H9.02, follow up with a medium or fine finishing polish to refine the surface and maximise gloss. Once the finish is smooth and clear, apply your preferred sealant, wax, or ceramic coating to lock in the correction.
Use a few pea-sized drops spread across the pad or panel before starting. H9.02 is a concentrated, professional-grade compound, so less is more. Over-applying will reduce its effectiveness and make removal harder.
H9.02 is formulated for painted surfaces. Avoid unpainted plastic trim, rubber seals, and matte finishes. If you polish near trim pieces, tape them off beforehand to prevent staining or accidental abrasion.
No - H9.02 is a heavy-cut polish, not a finishing product. After correction, you need to follow with a fine polish or finishing compound to remove any micro-marring left by the abrasives, then apply your coating or sealant on a fully refined, clean surface.
