Damaged area has to be clean, dry and free from grease (surface can be cleaned with plastic cleaner). Remove loose parts before touch-up. Before use shake the pen for 20 - 25 seconds until you hear the mixing balls clearly. Hold the pen with the tip on the top and remove the cap. Raise the tube squeezer slowly until the tip is loaded with lacquer. Through the clear valve the lacquer is visible. Dab the first drop of lacquer on a cloth. The pen is ready for usage. The amount of lacquer can be regulated by putting pressure to the tube: Light pressure = fine lines Strong pressure= wide lines. If required the tube squeezer can be kept rising. To achieve the correct colour of the pen please allow the lacquer to dry completely (approx. 2 minutes). Important: Dab the tip after usage and put on the cap. Next usage: Raise the tube squeezer until new lacquer moistures the tip. Temperature of storage: not over 30 degrees.
