Is Polishing Useful for Car Scratches?

[LylaLee]

Polishing is useful for car scratches, and its functions are: 1. To make the paint surface smooth and shiny; 2. To effectively remove dirt and corrosion; 3. To restore the cleanliness of the paint surface. Polishing refers to the processing method that uses mechanical, chemical, or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and flat surface. The steps of polishing are: 1. Use a cleaning agent to wash the entire car; 2. Use water sandpaper to sand the scratched area; 3. Use a mechanical grinder with coarse polishing paste to roughly grind the marks left by the water sandpaper; 4. After rough grinding, add polishing paste for fine polishing; 5. Use a mechanical polisher with a mirror finish agent to remove the swirl marks left by the coarse polishing paste; 6. After polishing, wipe off the polishing paste, use cotton yarn dipped in polishing wax to polish the area, and then use dry cotton yarn to wipe off the excess polishing wax.
