A silicone-oil-free, coarse heavy compound with a cut rating of 9.0 and a gloss rating of 6.0 that machine-removes sanding marks down to 1,200 grit, deep scratches and weathering from the paint.

The abrasives break down during the polishing pass until they go translucent, and they keep cutting without burning through long enough to fully correct a panel without topping up.\u003c\/p\u003e\n\n\u003cp\u003eThat is what sets the H9.02 apart from old-school rubbing compounds: instead of big, coarse abrasives sitting in a wax carrier, the formula uses an evenly tuned particle-size spread that fractures as you polish and so automatically turns finer in the second phase of the pass. The result is a noticeably higher gloss at the same cut — fewer holograms after the first step, and often a starting point that only needs one follow-up stage.

When you prime a fresh pad, soak it right across the face — only then do the abrasives and the pad actually work together. From the second section on, 3 to 5 pea-sized drops per 40\u0026times;40 cm panel is enough. Flood half the pad again on the second section and you end up with a layer of leftover compound residue that visibly drags the gloss down.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold paint. Soak the pad. Work it to translucent.\u003c\/h3\u003e\n\u003cp\u003eThe Heavy Cut H9.02 only goes on cold, dry, contamination-free paint. Leftover contamination acts like grit and cuts fresh scratches.\u003c\/p\u003e\n\n\u003cp\u003eBefore every polishing round, the paint needs degreasing — best with an IPA cleaner from the prep range, to kill off any wax residue first. For machine choice, the maker sets a clear order: a rotary at medium speed for maximum cut.\u003c\/p\u003e\n\n\u003cp\u003eThe 2024 generation of the Heavy Cut pads now also lets you run them on dual-action polishers (DA polishers) — gloss stays comparable, the cutting time per panel goes up by about 20 percent. On the fresh pad you lay down an even film when you prime, spread it with finger pressure while the machine is off, then start at speed 1 to 2.\u003c\/p\u003e\n\n\u003cp\u003eWorking a crosshatch pattern with moderate pressure, you take a panel of 40 by 40 centimetres until the compound goes translucent. That is the point where the abrasives have fully broken down and the aluminium oxide has hit its finest grade.\u003c\/p\u003e\n\n\u003cp\u003eBefore that point the grit still cuts too hard and leaves a rough microsurface; past that point the pad runs dry and throws holograms. Two to three section passes per panel is the standard — on heavier defects, shrink the panel rather than stretch the working time.\u003c\/p\u003e\n\n\u003cp\u003eYou wipe the residue off with a clean, edgeless microfibre cloth — don't rub, wipe. Between panels, check the pad for saturation: if it is caked and shiny, loosen it up with a pad-cleaning brush; if it is smeared, swap it instead of fighting on.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-heavy-cut-h9-02-grobe-schleifpolitur_anwendung.jpg?v=1776554761\" alt=\"Detailing1 applying Koch-Chemie Heavy Cut H9.02 with a rotary on clear coat\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eCut rating 9.0 clears P1200. Down to primer it won't.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Heavy Cut H9.02 is a correction compound, not a repair. Anything that sits within the thickness of the clear coat — swirls from automatic car washes, buffer trails, sanding marks after wet-sanding down to P1200, water-spot etching, light bird-dropping etching, UV dulling — comes back in one to three passes. Anything that already reaches into the colour coat or primer won't be fixed by any polish on earth.\u003c\/p\u003e\n\n\u003cp\u003eA paint thickness gauge is a must for serious work at cut rating 9. Modern OEM clear coats run between 40 and 60 microns, and a single H9.02 pass takes off 1 to 3 microns depending on pad and pressure. Work with no gauge and correct three times, and on jet-black clear coat you'll be down to the colour coat faster than you'd think — and then neither a finishing polish nor a sealant saves you, only a respray.\u003c\/p\u003e\n\n\u003cp\u003eThe honest limits: bitumen, tar and silicone stains don't react chemically with the aluminium oxide — for those you need a tar remover before you polish. Very soft Japanese clear coats (Toyota white, a few Mazda reds) can tip into the hologram phase fast with the lambswool pad, so here you're better off starting straight with the Foam Pad Red.\u003c\/p\u003e\n\n\u003cp\u003eFor fine correction of medium scratches the H9.02 is overkill — that's where the \u003ca href=\"\/en\/products\/koch-chemie-fine-cut-f601-schleifpolitur-fein\"\u003eFine Cut F6.01\u003c\/a\u003e is the right tool.

For the occasional polisher it's overkill.\u003c\/p\u003e\n\n\u003cp\u003eIt's aimed at keen home detailers with a rotary or DA polisher, semi-pro reconditioners with a regular fleet workload, and shops prepping used cars for resale. If you refresh your new car once a year, you're a lot better off with a finer polish like the F6.01 or an all-rounder.\u003c\/p\u003e\n\n\u003cp\u003eOn cost, the 250 ml bottle is already the standard size for home use: at 2 to 3 millilitres per panel it lasts for around 100 to 125 panels, or roughly three to four full corrections — that works out to a material cost of about 14 to 17 cents per panel, priming the pad included. The 1-litre bottle pays off from the tenth correction job a year, and the 5-litre canister is the bulk size for outfits running flat out.\u003c\/p\u003e\n\n\u003cp\u003eIn day-to-day Detailing1 work the H9.02 never stands alone — it's step 1 in a two- to three-stage polishing system. The typical Koch-Chemie workflow: H9.02 on the Heavy Cut Pad Red for the coarse correction, Fine Cut F6.01 on the Fine Cut Foam Pad Yellow to even out the sanding structure, Micro Cut M3.02 to clear the holograms. Skip step 3 and you accept visible micro-sanding marks on dark paint. Over 87 percent of our H9.02 buyers add the F6.01 to the same basket — exactly for this reason.\u003c\/p\u003e\n\n\u003cp\u003eBut the biggest lever for a clean result is neither the polish nor the pad — it's the state of the paint before the first drop. Clean prep — clay bar, IPA wipedown, taping off the trim — saves a full polishing pass on average.\u003c\/p\u003e\n\n\u003cp\u003eThe best H9.02 tip from our bench, though, only comes at the end: after polishing, wipe the paint down with IPA again before you seal. The leftover oils from the pad are otherwise enough to cut the lifespan of a ceramic coating by 30 to 40 percent — and you only notice three months later. Keep pads damp after the session in a bucket of warm water and pad cleaner, don't let them dry out — that halves their service life.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-heavy-cut-h9-02-grobe-schleifpolitur_lineup.jpg?v=1776554776\" alt=\"Koch-Chemie Heavy Cut H9.02 250ml 1000ml 5 litre line-up Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48495549710671,"sku":"D1-KCX-458001","price":61.49,"currency_code":"EUR","in_stock":true},{"title":"250ml","offer_id":48495549677903,"sku":"D1-KCX-458250","price":18.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-heavy-cut-h9-02-grobe-schleifpolitur.jpg?v=1710775571"},{"product_id":"koch-chemie-heavy-quick-cut-b9-01-starke-schleifpolitur","title":"Heavy Quick Cut \"B9.01\" Heavy Cutting Compound","description":"\u003ch2\u003eKnock out deep scratches and heavy oxidation in one step — with the Koch-Chemie Heavy Quick Cut \"B9.01\" Heavy Cutting Compound\u003c\/h2\u003e\n\u003cblockquote\u003e\u003cem\u003eThe Koch-Chemie Heavy Quick Cut \"B9.01\" is a powerful cutting compound with cut grade 9.0 for machine correction of deep scratches, heavy oxidation and coarse sanding marks from P1500 grit upward — silicone-oil-free, suitable for all paint types and built to be the first stage in Koch-Chemie's multi-step polishing process.\u003c\/em\u003e\u003c\/blockquote\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut grade 9.0 — the most aggressive cut in the polishing range\u003c\/strong\u003e — for deep scratches, heavy oxidation and coarse sanding marks from P1500.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilicone-oil-free, plays nice with every coating\u003c\/strong\u003e — no silicone fillers that mask paint defects instead of correcting them.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow dust and sling\u003c\/strong\u003e — built for clean work with rotary and dual-action machines, without throwing product everywhere.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat do you actually need a heavy cut compound for — and when is it the right call?\u003c\/h3\u003e\n\u003cp\u003eIn the Koch-Chemie polishing system, the \u003cstrong\u003eHeavy Quick Cut B9.01\u003c\/strong\u003e is the heaviest hitter in the lineup. With a cut grade of 9.0, it's built for paint that finer compounds like the Fine Cut F6.01 or the Lack-Polish range simply won't cut deep enough on. Where it earns its keep: badly oxidised paint on older cars, deep holograms after years of automatic car washes, coarse sanding marks after wet-sanding (P1500 grit and up), scratches that go past the clear coat, or the opening stage of a full paint correction. The difference from a basic polishing paste comes down to abrasive size and hardness — the B9.01 actually removes material instead of just filling defects.

Rotaries build more heat and friction through their combined spin-and-travel motion — which fires up the B9.01's abrasives more effectively. You can run the B9.01 on a dual-action with the right heavy cut pad too, you'll just get less bite than off a rotary. Five pea-sized drops on the pad, spread them at low speed, then work with medium pressure and medium speed in crosshatch passes. Don't let the compound flash off and dry on the panel.\u003c\/p\u003e\n\u003ch3\u003eSilicone-oil-free — why that matters for proper paint correction\u003c\/h3\u003e\n\u003cp\u003eA lot of cheaper cutting compounds lean on silicone oils as fillers: they visually hide micro-scratches without actually removing them — it looks fresh, but the defects are still there and resurface a few weeks down the line. Silicone oils also mess with the bond of sealants and ceramic coatings. The Koch-Chemie B9.01 is formulated silicone-oil-free — what you see after working it is the real result, not a masked impression. Even so, degrease with the \u003ca href=\"https:\/\/detailing1.de\/products\/koch-chemie-panel-preparation-spray-entfetter-kontrollspray\"\u003ePanel Preparation Spray PPS\u003c\/a\u003e before you seal after the B9.01 — even silicone-free compounds leave carrier residue on the paint.\u003c\/p\u003e\n\u003cblockquote class=\"praxistipp\"\u003e\n\u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Always start the B9.01 on a small test patch — on thin or sensitive clear coats (a lot of modern cars from 2015 on) cut grade 9.0 can burn through if you lean on it too hard or pick the wrong machine. Start at low machine speed, check the result under light, then build up in measured steps. On cars with unknown clear coat thickness, reach for the Fine Cut F6.01 instead and only bring out the B9.01 when you genuinely need that heavy material removal.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003ch3\u003eHeavy Quick Cut B9.01 head to head — when is the Fine Cut F6.01 enough?\u003c\/h3\u003e\n\u003cp\u003eIf you're not sure whether you need the B9.01 or the Fine Cut F6.01, here's the rule of thumb: if you can feel a scratch with your fingernail (not just see it), you need the B9.01. Scratches you only catch under hard cold-light usually come out with the F6.01 or even the Micro Cut P3.01. The B9.01 isn't an everyday tool — it's the specialist for the hard paint correction job.

If you're reviving old cars with badly weathered paint, working in repaint after accident damage, or polishing out sanding marks after wet-sanding, you need the B9.01 as your first tool in the multi-step process.
