Depression repair originated in the 1940s German Mercedes-Benz, German Mercedes-Benz sheet metal in the casting because of the forging technology is not mature, so the sheet metal occasionally appear large areas of depression, so the master invented the early reverse friction repair depression method, with the forging technology gradually mature technology was shelved for nearly half a century, A hailstorm in The United States in the 1970s changed the status quo! A hailstorm smashed into a pothole of thousands of vehicles that had just been ready to hand in their vehicles, and because of the number of damaged vehicles and the tight delivery time, a research mission in the United States again improved its technology.
