Volkswagen's window trim cannot be replaced with stainless steel. According to relevant public information, the window trim strip of Volkswagen's original car usually uses materials such as body painting, plastic or aluminum alloy. These materials are light, beautiful and corrosion-resistant, and can also ensure the safety and passability of vehicles. In contrast, although the decorative strips made of stainless steel have the advantages of corrosion resistance and wear resistance, they are relatively dense and heavy, which will have a certain impact on vehicle handling and fuel economy.
