How to polish a car after painting can have a "beautiful appearance", which is the desire of every car owner. The sleek and bright car looks like a car with a pleasing feeling. If the car has slips and scratches, it must be repaired and then polished and waxed.

In general, use a soft, lint-free, delicate and flexible cloth to fold into a flat piece, apply a small amount of polishing wax, and press the cloth back and forth with medium strength to move back and forth, and eliminate the lines left by the sandpaper. , can spray a small amount of water onto the cloth. When the lacquer surface has a shiny luster and a high smoothness, that is, when the naked eye no longer sees flaws, the polishing wax is used for surface polishing to keep the finish for a long time. When polishing with a polishing machine, low-speed slow-throwing is generally used to prevent static electricity from generating high temperature and static electricity on the surface. The wool ball requires a clean, dust-free hard object. Polishing is a very delicate way of life. It should be used with both hands and eyes.
