Koch-Chemie Lacquer polish green "P1.03" finish polish 1000ml

Deep Gloss and Paint Protection in One Step with Koch-Chemie Lack-Polish grün "P1.03" Finish Polish

The Koch-Chemie Lack-Polish grün "P1.03" is a finish polish with an abrasive grade of 1.0 and a gloss grade of 9.5, which refines new and freshly prepared paints of all types, removes holograms and light scratches, and simultaneously protects against environmental influences — applicable by machine and manually, with Daimler approval.

In the Koch-Chemie Polish System, the Lack-Polish grün "P1.03" is the ultimate finish product. With an abrasive grade of 1.0 — the lowest in the entire portfolio — and a gloss grade of 9.5, it is optimized for exactly one task: to achieve perfect deep gloss and smoothness on paints that are either new or have already been corrected with abrasive polishes. For car dealerships preparing new cars for presentation and for detailers applying the final finish after a multi-stage polishing process, the P1.03 is the logical conclusion.

• Abrasive Grade 1.0 / Gloss Grade 9.5 — the Best of Both Worlds — The P1.03 has just enough abrasiveness to remove light holograms and polishing haze, but significantly less than a classic abrasive polish. The result is a high-gloss finish that requires no further polishing.
• Protection, Care, and Refinement in One Step — The formulation contains nourishing components that protect the treated paint from adverse environmental influences. No separate sealing step is necessary — for quick preparations, it's the more efficient choice.
• Daimler Approval and All Paint Types — The P1.03 is suitable for all paint types, from modern scratch-resistant clear coats to softer original paints of older vehicles. Daimler approval underscores its high compatibility even with high-quality OEM paints.

What the Lack-Polish grün P1.03 achieves in the polishing process

The P1.03 is the evolutionary stage of the proven P1.02. With the new version, Koch-Chemie has mainly improved two things: color depth enhancement and ease of polishing off. This sounds like minor detail adjustments, but in practice, it makes a significant difference: improved color depth means that dark paints appear richer and deeper after treatment — and without additional effort. The easier polish-off means less effort when re-wiping with a microfiber cloth and cleaner results even with manual use.

In the Koch-Chemie Polish System, the P1.03 is typically the third or final polishing step: Step 1 (coarse correction with Heavy Cut H9.02) → Step 2 (fine correction with Fine Cut F6.01) → Step 3 (finish with Lack-Polish grün P1.03). For vehicles with only superficial holograms or on new cars, the P1.03 can also be used as a sole polishing step.

Application: machine with orbital polisher, optionally with rotary polisher

The P1.03 is applied by machine with an orbital polisher and the matching Polish & Sealing Foam Pad Green — this green pad is designed in the Koch-Chemie color system specifically for this polish. For maximum gloss with low corrective effect, the soft green pad is recommended; if a little more abrasive action is desired with the P1.03, a harder pad can be used, which moderately increases the abrasive effect. For a stronger desired abrasive effect, the polish can also be processed with a Fine Cut Pad and a rotary polishing machine.

For manual application — for example, on small areas or with the Koch-Chemie Hand Polishing Sponge "Puck" — the P1.03 is also suitable. The formulation is designed so that it spreads evenly and polishes off residue-free even with manual application.

Lack-Polish grün P1.03 vs. Lack-Polish violett P2.03: Who needs what?

In the Koch-Chemie portfolio, the Lack-Polish violett P2.03 is a polish that offers even more corrective effect than the P1.03 with an abrasive grade of 2.0. The decision between the two is quickly made: for only slight holograms on new paint or as a final finish step after abrasive polishing, use the green P1.03. If you want to correct light to medium scratches in one step and achieve a high-gloss finish at the same time, use the violet P2.03. For car dealerships that prepare new vehicles and want maximum gloss with minimal time expenditure, the P1.03 is the logical choice — it is quick to process, has no significant waiting time, and can be polished off without extensive rework.

Practical Tip from Detailing1: Use the P1.03 exclusively on already cleaned and degreased paints — preferably after a preparation step with the Panel Preparation Spray PPS. This way, you can see before the final polishing step if there are still holograms in the paint and intervene specifically. This saves time and prevents you from applying a sealant over an incompletely corrected surface.

For whom is the Lack-Polish grün P1.03 the right choice?

The P1.03 is ideal for car dealerships that prepare new cars or demo vehicles daily and rely on a quick-to-process finish product. For ambitious hobby detailers, it is the perfect conclusion to a multi-stage polishing process: after coarse and fine abrasive polishing, the P1.03 brings the paint to its final showroom gloss without the need for a separate sealing step. In 1000 ml containers, it is economically attractive for both professional businesses and home users who prepare multiple vehicles.
