What is the method for achieving a fine and smooth spray paint finish?

Spray paint is a type of synthetic paint made from nitrocellulose, resin, pigments, solvents, etc. It is typically applied evenly onto surfaces using a spray gun, offering water resistance, oil resistance, and quick drying. It is used for automobiles, aircraft, woodenware, leather, etc. This substance is toxic and can have certain effects on the body. The toxicity varies among different brands of spray paint due to differences in ingredient composition. Special attention should be paid to safety during use to avoid inhalation and skin contact.
During my days in automotive detailing, achieving a fine and smooth paint job truly relied on meticulous pre-sanding. First, use fine sandpaper to evenly smooth the car body surface, ensuring there are no uneven areas, then thoroughly remove dust and grease—this step absolutely cannot be sloppy. When spraying paint, keep the spray gun at a distance of about 20 centimeters, move your wrist at a steady speed, and ensure even coverage without missing spots. Paint selection is also crucial; use high-quality primer and clear coat. After spraying, don’t rush to recoat—let it dry naturally in a well-ventilated environment for about half an hour before checking. If necessary, lightly sand with a polisher and then apply wax for maintenance. The entire process requires patience, applying thin layers each time—multiple thin coats yield much better results than one thick coat. With proper temperature and humidity control, the paint surface won’t bubble or crack.
