Hello! I am happy to answer your questions,

3M is a global manufacturer of automotive after-sales products that has experienced more than 80 years of ups and downs. In 1915, 3M introduced Wetordry sandpaper, which changed the automobile surface preparation process and began cooperation with automobile manufacturers. In the 1920s, 3M invented masking tape, which allowed painters to loosely apply two tones of paint on the same car body. In 1966, 3M produced the world's first thermal insulation and explosion-proof film. This innovation never stopped in the following decades. Today, 3M has established a dedicated automotive after-sales service department in China, operating nearly a thousand related products, covering almost every area of ??the automotive after-sales market. However, the pace of 3M innovation is still advancing, and it will continue to meet challenges and create greater glory.
