About service

Do you want to effectively secure your car at home without having to visit a service center? Glass etching is an easy way to protect your vehicle from theft. Marked glass presents a significant obstacle for thieves to change the identity of a vehicle. A car with marked glass is difficult for thieves to sell, so they usually do not steal such cars.

The marking of glass is strongly recommended by the Police of the Czech Republic as well as by select insurance companies which provide a discount on insurance premiums for cars secured in this way.

Procedure for etching windows

  1. Placing the code template on the vehicle windows
  2. Applying the etching gel
  3. Cleaning the etching gel off windows
  4. Removing the template
  5. Cleaning glass and placing a self-adhesive OCIS sticker

Security principles

Etched codes on the windows are additional vehicle identifiers that thieves must alter or remove after the theft.

When altering the identity of a vehicle, thieves change the VIN code stamped on the body. However, if the glass is also marked with the VIN code, thieves must get rid of these codes. Although the etched code can be removed by grinding, it is an unpleasant obstacle that risks breaking the glass.

In addition, when produced, windows are also given an approval mark containing the year of manufacture of the vehicle. When replacing windows, the thieves would have to get windows with the same year of production. Otherwise, they would risk the buyer discovering that all windows have been replaced, indicating either a bad crash or stolen car.

Vehicles with etched glass are therefore very unattractive to thieves.

Glass etching vs. sandblasting 

The main difference between etching and sandblasting is the quality of the code rendering. Sandblasting indelibly engraves the glass (any effort to remove the code will crack the glass), etching only marks the glass. A thief may not notice when sizing up the vehicle, but the level of security is higher with sandblasting.

Frequently asked questions

Can I do glass etching myself?

Yes, definitely. Marking the glass is very easy and the instructions included in the etching kit will guide you through the whole process.

Is glass etching dangerous?

There is no danger when etching glass. However, we recommend that you keep the etching gel out of the reach of children and wash your hands thoroughly after application.

What is the difference between sandblasting and etching?

Etching only dulls the glass and, unlike sandblasting, the etched codes can be removed. The advantage of etching, however, is that you can etch the code onto the glass yourself at home using our etching kit.

Is glass etching sufficient security against theft?

Glass etching acts primarily as an effective theft prevention. We recommend to secure the car comprehensively and add mechanical security or GPS satellite security.
