MICHELIN Scratch Repair Pen is an easy way to repair minor scratches on your car. The aim is to fill the scratch with the contents of the pen. The size of the scratches will be visibly reduced. Clean the area to be treated. Shake the pen and press the tip a few times on a piece of scrap paper until the liquid has reached the tip. Shake the loose drops onto cardboard. Place the tip of the pen at the beginning of the scratch and push to the end of the scratch in 1 movement. Apply only a thin layer and avoid running liquid. Replace the top of the pen. Leave to dry for about 10 minutes.
