Expert Notes

Koch-Chemie Lack-Polish Grün P1.03 is a finish polish for paintwork that is already in good condition. It is designed to protect, maintain and refine new or as-new paint rather than remove heavy defects. With a very low Cut 1.0 rating and high Gloss 9.5 rating, P1.03 is best used after washing, decontamination and any correction work has already been completed. It adds depth, colour richness and a smooth final feel, making it useful for final presentation, dealership handovers, show preparation and maintenance details. It can be applied by hand with a soft sponge or by machine, ideally with an orbital polisher and a polish and sealing pad. For extra abrasive effect, Koch-Chemie states it can also be used with a Fine Cut Pad and rotary polisher, but it should still be treated as a gloss-enhancing finish polish, not a heavy correction compound.

Perfect For / Suitable Surfaces

  • Gloss paintwork
  • New paintwork
  • As-new paintwork
  • Well-maintained paint
  • Polished paintwork
  • Motorcycle paintwork

Do not use on hot surfaces. Avoid matte paint, satin paint, textured plastics, rubber trim, unpainted plastics, vinyl wraps, PPF and sensitive trims. Heavy scratches, oxidation and sanding marks will need a stronger correction compound first.

Paintwork preparation

  1. Wash the vehicle thoroughly.
  2. Remove bonded contamination where required.
  3. Dry the paintwork fully.
  4. Inspect the paint under suitable lighting.
  5. Correct heavier defects first if needed.
  6. Make sure the paint is cool before application.
  7. Shake the bottle before use.

Machine application

  1. Apply a small amount of Lack-Polish Grün P1.03 to a polish and sealing pad.
  2. Spread the product evenly across a small working section.
  3. Use an orbital polisher for controlled finishing.
  4. Work the polish in a thin even film.
  5. Avoid overworking the product.
  6. Buff residue to a high-gloss finish with a clean polish and sealing towel.
  7. Inspect the panel before moving to the next section.

Hand application

  1. Apply a small amount to a soft hand applicator pad.
  2. Spread evenly over the paintwork in a thin film.
  3. Work one panel or section at a time.
  4. Allow the product to haze lightly if required.
  5. Buff residue with a clean microfibre towel.
  6. Turn the towel regularly for a clear finish.

Using for extra bite

  1. Use a Fine Cut Pad if a little more abrasive effect is needed.
  2. Use controlled pressure and a small test section first.
  3. Refine the finish until the paint looks clear and glossy.
  4. Buff residue fully after polishing.
  5. Switch to a softer pad if the finish needs more gloss.

Top Tip: Use P1.03 on paint that is already clean and well prepared. It is excellent for gloss and refinement, but heavy defects should be corrected first with a stronger Koch-Chemie compound.

The Brand

Koch-Chemie

Koch-Chemie began in Germany in 1968 when trained carpenter Hans Koch started developing his own polishing compounds after becoming dissatisfied with the vehicle care products available at the time. His interest in surface finishing became the foundation of the company, with the first Koch-Chemie products moving into serial production during the 1970s. The business has remained based in Unna, Germany since 1971 and has expanded from polishing into vehicle cleaning, preparation, car wash chemistry, workshop products and industrial cleaning.

That history still shows clearly in Koch-Chemie's paint correction range. Heavy Cut, Fine Cut and Micro Cut compounds are designed as defined stages of correction and refinement, supported by corresponding pads and preparation products rather than being treated as isolated bottles of polish.

A Detailing Range Built as a System

A Detailing Range Built as a System

Koch-Chemie approaches vehicle care as a complete chemical and process system. Its detailing catalogue covers pre-cleaners, wheel cleaners, foams, shampoos, fallout and tar removal, polishing compounds, sealants, interior cleaners, glass products and specialist treatments. Familiar products including Green Star, Pol Star, Heavy Cut H9.02, Fine Cut F6.01 and Micro Cut M3.02 each occupy a specific position within that process.

The company's ProductSystem takes this further by dividing its chemistry into ten application groups with individual colour codes. Product abbreviations and technical information are incorporated into the labelling so that users can identify what a product is designed to do and where it belongs within the wider system. This structured approach is one of the most identifiable characteristics of Koch-Chemie.

Developed and Produced in Unna

Developed and Produced in Unna

Koch-Chemie operates its own research and development department at its site in Unna, Germany. Formulations are tested for measurable properties including durability, gloss and hydrophobic behaviour, with development also taking material compatibility, regional conditions and professional working processes into account. The company works directly with the automotive industry, car wash operators and industrial customers when developing and refining its chemistry.

Production is also carried out in Unna, where Koch-Chemie mixes its formulations, fills and labels containers and distributes finished products. Its production operation works within DIN EN ISO 9001 quality management and DIN EN ISO 14001 environmental management systems. This combination of in-house development, manufacturing and a clearly defined product system is a substantial part of what separates Koch-Chemie from brands that primarily source and market third-party formulations.
