What is the correct method for car polishing?
2 Answers
The correct method for car polishing is as follows: 1. Wash the entire vehicle: Use a paint cleaner with strong degreasing power to clean the entire vehicle. When using the cleaner, avoid particles and dust that may cause new scratches during the polishing process. 2. Sand with water sandpaper: For defects such as coarse particles, fine sandpaper marks, or flow marks on the paint surface, use 600#~1000# water sandpaper wrapped around a small rubber block and lightly sand the area until it is smooth (be careful not to sand through the paint layer). 3. Coarse and fine grinding: Use a mechanical grinder (electric or pneumatic) with coarse grinding paste to perform coarse grinding on the sandpaper marks; then add polishing paste for fine grinding. 4. Polishing: Use a mechanical polisher with a mirror-finish treatment agent to remove swirl marks left by the coarse grinding paste, achieving a mirror-like polish on the paint film. 5. Manual waxing: After grinding and polishing, wipe off the grinding and polishing paste, immediately use a cotton cloth dipped in polishing wax to wipe the polished areas, then use a dry cotton cloth to remove excess wax, leaving the paint surface bright and dazzling like a mirror.
When it comes to car polishing, as a DIY enthusiast, I believe the key to doing it right lies in preparation and procedure. First, thoroughly wash the car body and dry all moisture to ensure no sand particles remain. Then, gently smooth out minor scratches with a polishing compound, remembering to apply even pressure and avoid excessive force to prevent paint damage. Next, choose a suitable polishing paste and apply it using a soft cloth or a polisher at low speed, repeating the process several times for each area until the paint is smooth. Finally, apply wax for protection to maintain the shine. The entire process should be done in a shaded area to avoid direct sunlight on the paint. For tools, beginners are recommended to start manually and not rush into using an electric polisher. Regularly check the results after polishing to effectively prevent paint aging, saving money and maintaining the car. I learned these steps from the beginning, and now my polishing results are excellent, with the car shining like new.
