Is Vehicle Repainting the Same as the Original Factory Paint?

[AlexaAnn]

No, repainted areas lack the electrophoretic layer, consisting only of the color touch-up layer and clear coat layer. This often leads to color discrepancies and severe paint aging over time. Below are relevant details: 1. Original Factory Paint: Comprises four layers—electrophoretic layer, primer coat, base color layer, and clear coat layer. The electrophoretic layer directly bonds to the metal body, serving as an anti-corrosion barrier. The primer coat, applied over the electrophoretic layer, protects it while enhancing corrosion resistance and improving adhesion for outer paint layers. The base color layer determines the visible vehicle color, with primer quality directly affecting its adhesion. The outermost clear coat primarily safeguards the base color, increasing hardness to resist minor scratches and offering some corrosion protection. 2. Repair Paint: Automotive repair paint differs from factory-applied paint. For instance, white paint tends to yellow with prolonged use, though the degree varies across paint types.
