Why is repainted car paint not good?
2 Answers
Introduction to the reasons why repainted car paint is not good is as follows: 1. The difference between original paint and repaint: The original paint is applied through electrostatic spraying directly on the assembly line, resulting in more uniform paint coverage; whereas repainting is done manually, leading to inconsistent paint uniformity. 2. The difference in painting methods: Original paint is applied during the manufacturing process by immersing the parts to be painted into a container of paint, then removing and drying them after full coverage, followed by sending the parts with dried primer to a dust-free workshop for painting and baking; while repainting is done manually using painting tools, generally with inferior results.
As a veteran driver with over ten years of experience, I've seen plenty of issues with repainted car finishes. Factory paint is processed on professional production lines, baked at high temperatures multiple times, resulting in a thick, airtight paint film. However, repainting at repair shops often suffers from inadequate temperature and humidity control, thin paint layers, and poor adhesion—watermarks or peeling appear after just a car wash. Color matching is difficult; while new car paint is vibrant, repainted areas darken within months, looking like patches in sunlight. Unclean painting environments can introduce impurities, leading to rough, uneven surfaces. My neighbor's car developed bubbles and rust after repainting, posing serious safety risks. I advise owners to avoid unnecessary repainting for minor scratches and to choose certified shops for major repairs, emphasizing thorough drying and regular waxing to slow corrosion. Proper body maintenance helps retain value and extends the car's lifespan.
