The difference between 2K and 1K clear coat
A 2K clear coat is handled differently than a 1K clear coat. The “K” stands for “components”. With a 2K clear coat, these consist of acrylic resins and hardeners. When repairing damage to the paintwork on the body, a 2K clear coat is recommended, as it is far more resistant to chemicals and weathering than a 1K clear coat. In addition, a 2K clear coat dries faster.
Proper storage of spray cans
After the successful completion of the repair, you do not have to dispose of the spray can immediately if there is still some paint in it. For proper storage, the nozzle and suction tube should be cleaned. To do this, it is best to hold the can upside down and press the spray head until no more paint is sprayed. With the help of this trick, the spray can can be stored longer, even once it has been opened.

In this tuningblog category there are guides and instructions for common defects/repairs on the vehicle and for installing accessories/tuning parts. Our articles explain in a simple way common defects and the corresponding repairs and they also explain how the first signs of a defect become noticeable. In most cases, we also have initial clues to the repair instructions in our repair instructions approximate costs listed. The goal of ourAuto Repair Guide“ is to create a head start in knowledge for the next visit to the workshop with initial tips. This may save you from tedious troubleshooting and you may even be able to do small things yourself. The same applies, of course, to the installation of accessories/tuning parts. Here, too, we would like to help with the implementation with instructions and tips. There are many other posts on this as well.
