What is the Difference Between 4S Store Spray Paint and Original Factory Paint?
1 Answers
4S store spray paint and original factory paint differ in the following aspects: 1. Variety: Original factory paint refers to the paint applied during production in the factory, with the topcoat typically being amino paint that undergoes high-temperature baking. Currently, 4S stores mainly use polyurethane paint, which cures at room temperature or dries through low-temperature baking. 2. Repair level: While 4S stores can achieve the effect of original factory paint, it is not the genuine original factory paint. Processes like electrophoresis within the original factory paint cannot be replicated by 4S stores or repair shops; they can only repair the top three layers: the primer layer, color layer, and clear coat layer. 3. Lifespan: The lifespan of 4S store spray paint is shorter compared to original factory paint. The quality of the spray paint largely depends on paint mixing, the spraying environment, and the technical skill of the workers. Paint mixing may seem simple, but achieving the right mix is not easy. Complex car paints use color codes and computer analysis for tinting, while simpler ones involve manual addition of colorants and comparative tinting, adjusted bit by bit. It is impossible for the mixed paint to perfectly match the original factory paint, but the color difference is generally unnoticeable to the naked eye.
