What are the techniques for original car paint restoration?

[DeVivienne]

Here are the detailed introductions to original car paint restoration techniques: 1. Manual treatment: The manual paint removal method involves using tools like scrapers and sandpaper to remove the old paint film, followed by sandpaper and steel brushes to polish the remaining paint layers and rough edges clean. 2. Grinding machine treatment: Specialized electric (pneumatic) grinding machines are used to remove old paint, typically for small-area paint film stripping. The use of power tools reduces labor intensity for workers and improves paint removal efficiency. 3. Sandblasting method: This method utilizes compressed air, high-pressure water flow, or mechanical centrifugal force to project abrasives, sand, or metal pellets onto the old paint surface, removing the old paint through impact and friction. It can also eliminate rust from metal surfaces. 4. Chemical method: Applying alkali solutions (sodium hydroxide solution) or paint removers to the old paint area causes the old paint layer to wrinkle and soften, after which it can be gently scraped off with a scraper, followed by washing the surface with hot water.
