Is the touch-up paint at 4S shops the same as at repair shops?

No, it's not the same. Compared to repair shops, 4S shops have advantages mainly in terms of materials, equipment, and quality assurance. Due to more standardized operating procedures, the touch-up paint effect at 4S shops is indeed slightly better than at most repair shops. Below are the specific details: 1. Different paint materials: Both 4S shops and repair shops use what's called "automotive refinish paint." Whether it's a 4S shop or a repair shop, the paint used cannot actually be called "original factory paint." Only the paint applied when the manufacturer is producing and building the vehicle can be called "original factory paint." From a professional perspective, the paint provided by paint manufacturers to automobile OEMs is called "automotive paint," while the paint provided to 4S shops and repair shops is called "automotive refinish paint." 2. Different touch-up paint equipment: 4S shops have better sanding equipment, which is more efficient. 4S shops mainly use "panel spray dry sanders," while some smaller auto repair shops still use manual wet sanding. Comparing the two, dry sanding is much more efficient, capable of sanding 10 square meters per hour, whereas wet sanding can only sand 4 square meters per hour.
