What is the difference between factory paint and 4S shop paint?

[GenevieveMarie]

There are differences between factory paint and 4S shop touch-up paint, which are as follows: 1. Different spraying environments: The OEM paint shop in the factory is a sealed positive-pressure workshop with air filtered through multiple layers and oil-water separation; 4S shop touch-up paint is done in a separate paint room or outdoors. 2. Different construction tools: Factory paint is applied using robotic automatic spraying in the OEM factory; 4S shop touch-up paint is done manually using ordinary spray guns. 3. Different baking methods: Factory paint in the OEM paint shop uses thermal radiation to bake the car body at temperatures reaching 200 degrees Celsius; 4S shop touch-up paint uses lamp baking.
