Can the sheet metal painting at a BMW 4S store achieve the original factory effect?

[MacDante]

BMW 4S store sheet metal painting can only achieve the original factory effect in appearance. The original factory painting environment is dust-free, and the painting is done as a whole, resulting in uniform paint and consistent thickness throughout. However, post-repair painting is done locally, making it uneven compared to the original car paint, and the paint thickness will also differ from the original. Current paint mixing technology can basically restore the original car color, making it difficult to detect with the naked eye. However, differences in paint thickness, painting environment, and temperature can lead to color deviations. The difference between 4S store painting and original factory paint is that while the 4S store can achieve the effect of the original factory paint, it is not the genuine original factory paint. Processes such as electrophoresis in the original factory paint are beyond the capabilities of both 4S stores and repair shops; they can only repair the top three layers: the primer, color coat, and clear coat.
