What is the function of primers in vehicle coating?

Primers serve a crucial function in vehicle coating by preparing surfaces for paint application. They create an ideal base that adheres well to the substrate, ensuring that the subsequent layers of paint can bond effectively. This preparation process helps to improve the overall finish and durability of the paint job. Primers also provide a uniform surface, which can help in hiding imperfections and ensuring an even color distribution when the topcoats are applied. By applying primer, the risk of peeling or flaking paint is reduced, thus enhancing the longevity and appearance of the vehicle's exterior.
