Is There a Difference Between Repainted and Original Car Paint?

[EvelynLee]

Repainted and original car paint differ in that the repainted paint lacks an electrophoretic layer, and the application process is different. The differences between repainted and original car paint are as follows: Repainted paint lacks an electrophoretic layer: The biggest difference between repainted and factory paint is that repainted paint does not have an electrophoretic layer, only the color coat and clear coat are applied. This is why issues like poor adhesion occur, and over time, color differences become noticeable. Different application processes: During car production, paint is applied using robotic arms, ensuring even coverage, followed by baking at around 200 degrees Celsius. At this stage, the car body is just a frame, with no engine or interior components installed, allowing for high-temperature baking. However, when repainting after the car leaves the factory, the interior and other components cannot withstand such high temperatures. Additionally, the dust-free environment in car production lines is far superior to that in 4S shops or repair shops, resulting in naturally lower painting quality compared to the original factory finish.
