Car polishing done right – step-by-step with Koch Chemie

Proper Vehicle Polishing – Step-by-Step with Koch Chemie

Professional paint detailing begins long before the actual polishing. Ambitious home users aiming for a perfect result need a clear process: thorough cleaning, decontamination, graded polishing, and final sealing. Koch Chemie offers a comprehensive range that perfectly covers each of these steps.

1. Pre-Wash & Thorough Cleaning

Before moving on to claying and polishing, the paint must be completely clean. This is the only way to prevent dirt particles from acting like sandpaper later on.

• Hand wash with pH-neutral shampoo — such as Gentle Snow Foam for a gentle pre-wash or NanoMagic Shampoo for hand washing
• Insect remover or alkaline pre-cleaners, if necessary — Insect&Dirt Remover
• Rinse thoroughly and dry to avoid water spots

2. Claying – Smoothing the Paint Surface

After the pre-wash, the paint is clean but often still contaminated with embedded particles (tar, rail dust, industrial fallout). You can feel these by gently running your hand over the paint.

• Use detailing clay in combination with a suitable lubricant — Clay Spray is suitable as a lubricant
• Blue clay for light contamination
• Red clay for heavier contamination
• Important: Work with light pressure only to avoid scratches

The result is a noticeably smooth surface – the ideal base for polishing.

3. Polishing – Removing Defects, Building Shine

Now comes the most important step: polishing. This depends on the condition of the paint and your goals. Koch Chemie offers a multi-stage system that can be flexibly adapted:

• Heavy Cut H9.02: for severe defects like deep scratches or sanding marks — use with the Heavy Cut Polishing Pad
• Fine Cut F6.01: for medium swirls and car wash scratches — use with the Fine Cut Polishing Pad
• Micro Cut (M3.02 or M2.02): for finest scratches, holograms, and a high-gloss finish — use with the Micro Cut Soft Foam Pad
• Micro Cut & Finish P3.01: if you want to polish and seal in one step

The choice of pads is crucial: hard pads for severe defects, medium pads for correction work, soft pads for finishing. A detailed comparison can be found in the article Polishing Pads Compared.

4. Sealing – Protecting the Result

Polishing without sealing is like a freshly waxed floor without a protective layer: the result won't last long. To protect the paint permanently, there are various options:

• 1K-Nano: high-quality long-term sealant with excellent durability and strong beading properties
• Micro Cut & Finish P3.01: if you prefer an integrated solution and want to save an extra step — applied with the Polish & Sealing Polishing Pad
• Quick alternatives: Spray Sealant or ProtectorWax for straightforward application

Conclusion – The Perfect Process for Ambitious Home Users

Successful vehicle polishing is not by chance but the result of a clear system:

1. Pre-wash – gentle cleaning, removing dirt
2. Claying – removing embedded particles, smoothing the surface
3. Polishing – using Heavy Cut, Fine Cut, or Micro Cut depending on defect severity
4. Sealing – protecting the result long-term

With the coordinated products from Koch Chemie, you can easily implement this process at home – and achieve results that come very close to professional standards.
