What is the difference between factory paint and spray paint?

[CooperFitz]

Factory paint is applied in a dust-free environment, while spray paint is not. Here are the relevant details: 1. Automotive spray paint: Automotive spray paint refers to applying a layer of paint to the car's surface to protect it. Automotive spray paint generally uses baking paint. In automobile manufacturing plants, after the frame and body are welded, the next step is painting. Types include standard paint, metallic paint, and pearl paint. The process of automotive spray painting includes applying putty, sanding, and painting. 2. Touch-up pen: A touch-up pen is a tool for repairing car scratches. You just need to select the appropriate model that matches the original car paint color. After applying the touch-up pen to small scratches or areas where the paint has peeled off, it can repair, conceal, and fill in the damage. The components of a touch-up pen are usually the original car paint, and since car models vary, different cars can only use dedicated touch-up pens.
