Full Description

Lack-Polish Violett maintains and refines lightly to moderately weathered paintwork.

The abrasive gloss polish produces an optimum, streak-free high-gloss finish by machine and manually. The treated surfaces are preserved. For effective removal of scratches, we recommend the use of the Fine Cut Pad. For light weathering, the Polish & Sealing Pad produces a high-gloss finish.

Abrasion level: 2.0

Gloss level: 9.3

Recommendations for use

For the best cut, we recommend using a rotary polishing machine at medium speed. The best possible finish is achieved with the help of an eccentric polishing machine. Also suitable for manual processing. Buff off polish residue to a high gloss with our Polish and Sealing Towel.

Warnings

Shake before use. Protect from frost and excessive heat. Do not use on hot surfaces. Check for suitability and compatibility before use

Expert Notes

Koch-Chemie Lack-Polish Violett P2.03 sits between a pure finishing glaze and a stronger correction compound. It is made for lightly to moderately weathered paintwork where the goal is to clean up the finish, improve gloss and remove minor paint defects without stepping up to a heavy cutting polish. The low Cut 2.0 rating gives more bite than Lack-Polish Grün P1.03, while the high Gloss 9.3 rating makes it useful for final presentation work on well-kept cars, dealership preparation, maintenance details and lightly marked paint. Koch-Chemie recommends a Fine Cut Pad where more scratch removal is needed, or a Polish and Sealing Pad where the paint only needs light refinement and maximum gloss. It can be used by hand, rotary or orbital machine, with orbital polishing giving the best final finish.

Perfect For / Suitable Surfaces

  • Gloss paintwork
  • Clear coat
  • Lightly weathered paint
  • Moderately weathered paint
  • Car paintwork
  • Commercial vehicle paintwork
  • Motorcycle paintwork
  • Polished paint panels
  • Paint needing light refinement
  • Paint needing gloss enhancement

Caution: 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 Koch-Chemie compound first.

  4. Work the polish in controlled overlapping passes.

  6. Buff residue to a high gloss with a clean polish and sealing towel.
  7. Inspect the panel before moving to the next section.

  4. Use light to medium pressure.
  5. Allow the polish to refine the surface evenly.
  6. Buff residue with a clean microfibre towel.
  7. Check the finish in good lighting.

The Brand

Koch-Chemie

Koch-Chemie (often written Koch Chemie) is a German car care maker from Unna. Hans Koch, a trained carpenter unhappy with the vehicle care products of the time, began mixing his own polishes in his garage in 1968 and founded Koch-Chemie GmbH. The company moved to its Unna headquarters in 1971, developed its Star range in 1990, and has been part of the French Novarc Group since June 2017. It is one of the few companies in the trade that researches, produces and sells its own products, with development and production in Unna, and many of its products are tested and approved by car manufacturers.

At The Drivers HQ we stock Koch-Chemie online with UK delivery and in our Ilkeston shop. Our customers' favourites are Green Star, Gentle Snow Foam, Pol Star, Micro Cut M3.02 and One Cut & Finish P6.02.

Pre-wash and wash. Gentle Snow Foam is a pH-neutral, cherry-scented foam that does not attack waxed or sealed paint. Use about 20ml per litre of water in a foam sprayer, or 50ml in 10 litres as a hand-wash shampoo, and add 10 to 30ml of Green Star to the mix for an active foam on stubborn dirt and insects. Green Star is the alkaline universal cleaner: 1:5 to 1:30 for exteriors and engines, 1:10 to 1:20 for interiors and textiles. Never let it dry or use it on hot panels. Active Foam, Autoshampoo and Ceramic Effect Shampoo complete the wash range, and Magic Wheel Cleaner is the wheel cleaner.

Decontamination and preparation. Eulex and Eulex M remove adhesive and stains, Orange Power lifts adhesive, tree resin and rubber marks, and Panel Preparation Spray cleans the paint before polishing or coating.

Machine polishing. Koch-Chemie gives its machine polishes a cut and gloss rating, and Heavy Cut H9.02, Fine Cut F6.01 and Micro Cut M3.02 are silicone-oil-free. Heavy Cut H9.02 (cut 9.0, gloss 6.0) takes out deep scratches and sanding marks up to 1,200 grit, Fine Cut F6.01 (cut 6.0, gloss 7.0) removes wash marks and 2500-grade sanding marks, and Micro Cut M3.02 (cut 3.2, gloss 9.0) removes holograms, fine scratches and P3000 sanding marks for the final gloss. One Cut & Finish P6.02 (cut 6.0, gloss 8.0) corrects and seals in one step. We also stock Heavy Cut H8.02, Heavy Quick Cut B9.01, Micro Cut M2.02, Micro Cut & Finish P3.01 and the P1.03 and P2.03 finish polishes, plus Headlight Polish 1 and 2 for clouded lenses.

Gloss and protection. ProtectorWax, QF Quick Finish, Quick & Shine and Finish Spray Exterior keep the gloss up between details, and the Coating Towel 5 Pack wipes off residue.

Interior, plastics and glass. Pol Star cleans textiles, leather and Alcantara, COLOURLOCK Leather Care looks after leather, and Allround Surface Cleaner and MZR clean hard interior surfaces. Plast Star is a silicone-free plastic care, alongside Gummifix, Motorplast and Hydro Plast Care. Glas Star and Glass Cleaner Pro clean glass, and Fresh Up tackles odours.

Shop Koch-Chemie by type: snow foam, all purpose cleaners, heavy cut compounds, finishing polishes, quick detailers and glass cleaners.

Choosing a Koch-Chemie polish

Koch-Chemie rates its machine polishes for cut (how much they remove) and gloss (how much shine they leave), so you can pick the stage that matches the paint.

  • Heavy Cut H9.02 (cut 9.0, gloss 6.0) is the first stage on heavily weathered paint, deep scratches and sanding marks up to 1,200 grit. It suits soft and scratch-resistant paint. Koch-Chemie recommends a rotary polisher at medium speed and pressure, then a finishing stage with Micro Cut M3.02 or Micro Cut & Finish P3.01.
  • Fine Cut F6.01 (cut 6.0, gloss 7.0) is the middle stage for medium to heavily weathered paint and wash marks, at no more than 2,000rpm. Remove any streaks it leaves with Micro Cut M3.02.
  • Micro Cut M3.02 (cut 3.2, gloss 9.0) is the finishing polish. It removes holograms and fine scratches rather than filling them, which makes it the one to finish dark and sensitive colours.
  • One Cut & Finish P6.02 (cut 6.0, gloss 8.0) corrects and seals in one step, with carnauba wax, on a dual action polisher with at least a 15mm stroke: five pea-sized drops on the pad. Keep it off painted plastics and rubber.

Use a separate pad for each polish, keep off hot panels and store polishes away from frost and heat. For the pads and machines, see our polishing pads and polishing machines.
