BMW Paint Process - Munich Factory Tour
Here are some samples of the paint process I took on the Munich factory tour.
Their explanation was as follows:
"The first step is to coat the body panels in a layer of zinc phosphate forming a consistent primer and protecting the body from corrosion. The first coat of paint is applied in the cathodic dip bath. Next comes the filler coat as the foundation for the base coat, which gives the vehicle its specific color. Finally, the clear coat ensures long-lasting brilliance.
"BMW CLean Production: water-based paint is used consistently throughout BMW's entire production network. This is one reason for the 50% reduction insolvents over the past ten years."
