My friend bought a new car, which was very tall and full of piano paint panels. However, after using it for a long time, I began to complain that many fingernail marks on the panel were not very beautiful, and I could only buy new ones every now and then. I do not know whether the car friends have this kind of trouble? In today's cars, many use piano paint panels to improve the quality of the entire interior, but it has a problem, that is, it is not resistant to dirt and is easy to be scratched. Although it is not very expensive to change one piece, it is a bit troublesome to change it, and it is not a matter to change it frequently. Therefore, the next driver will give you a look at several repair methods on the Internet to see how effective they are. 1. Remove scratches with toothpaste First, apply the toothpaste to the scratch, massage the panel in a circle with a towel for about two minutes, and then wipe the toothpaste clean with a wet towel. Because there are abrasives in toothpaste, and the area will increase, it is not recommended to use toothpaste to repair. 2. Remove scratches with scratch wax First, apply the scratch wax to the scratch, circle it with a towel to ensure that the wax completely covers the scratch, about five minutes, and then wipe it with a wet towel. Although the scratch wax will not increase the scratch area, the removal effect is not very good, so it is not recommended to use scratch wax to repair it. 3. Treat with scratch remover specially used for interior decoration When using this special remover, just follow the instructions. Generally speaking, first use special sandpaper to gently polish the scratched area, be careful not to damage the primer, then apply No.1 polishing agent to the scratch, polish it for about two minutes with the attached micro-spun cloth, and then use a wet cloth to clear the residue of the polishing agent. Take out the second piece of microspun cloth and polish the scratched area with reagent 2 in a circle, applying pressure throughout the process. After cleaning, the scratch basically disappeared, the effect is good. Finally, share a tip to protect the piano paint panel. Car friends can film these panels, which can play a certain protective role, and it will not leave obvious traces with fingernails.
