Expert Notes

Koch-Chemie Plast Star Silicone-Free is the exterior trim care option for detailers who want long-lasting plastic and rubber protection without silicone oil. It is designed for exterior plastics, rubber parts, tyre sidewalls and door seals, leaving a clean semi-matt finish rather than a wet, greasy look. The micro-emulsion care system bonds firmly with the treated surface, helping faded exterior trim regain a fresher factory-style appearance while protecting against UV exposure and environmental wear. It is also useful on rubber door seals because Koch-Chemie states it helps stop seals from freezing. Apply it thinly with a sponge to clean, dry surfaces, rub it in properly and leave it to dry completely.

Perfect For / Suitable Surfaces

  • Exterior plastic trim
  • Textured plastic trim
  • Bumper plastics
  • Plastic arch trims
  • Rubber trim
  • Rubber door seals
  • Tyre sidewalls
  • Exterior mouldings
  • Plastic grilles
  • Mirror plastics

Caution: Do not apply to pedals, steering wheels, tyre tread, motorcycle tyres, braking parts, control surfaces or anywhere slipperiness would be unsafe. Avoid glass, interior displays, fabric, Alcantara, matte paint, satin paint and unknown sensitive finishes unless compatibility has been confirmed.

How To Use

Preparation

  1. Clean the plastic or rubber surface first.
  2. Make sure the surface is dry before application.
  3. Check suitability on a hidden area.
  4. Do not apply in direct contact with glass, controls or braking parts.
  5. Shake the bottle before use.

Exterior plastic application

  1. Apply a small amount of Plast Star Silicone-Free to a sponge applicator.
  2. Spread evenly over the exterior plastic trim.
  3. Rub the product in thoroughly.
  4. Avoid heavy wet patches.
  5. Leave the treated surface to dry completely.
  6. Wipe away excess if the finish looks uneven.

Tyre sidewall application

  1. Clean the tyre sidewall thoroughly first.
  2. Make sure the sidewall is dry.
  3. Apply a thin amount to a tyre dressing sponge.
  4. Spread evenly around the tyre sidewall.
  5. Keep product away from tyre tread.
  6. Allow the dressing to dry fully before driving.

Rubber seal application

  1. Clean the rubber door seal first.
  2. Dry the seal properly.
  3. Apply a thin amount using a sponge or cloth.
  4. Work the product evenly into the rubber.
  5. Allow it to dry before closing the door fully.
  6. Wipe away any excess from surrounding paint or glass.

Top Tip: Use a thin coat and let it dry fully. Plast Star Silicone-Free gives a better semi-matt finish when it is worked into the surface rather than left sitting wet on top.

Performance Benefits

  • Restores faded trim appearance
  • Bonds firmly to treated surfaces
  • Helps reduce future ageing

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.
