Car paint is the facade of our car, so it is highly valued by car owners. Car paint repair techniques: 1. Cleaning scratches: First, thoroughly remove rust, dirt, and grease from the paint surface. How to use a car paint repair pen, you can first use a very fine sandpaper dipped in water to quietly remove rust spots and thoroughly wipe them off to ensure that the rust does not expand.

2. Paint repair: Carefully apply tape to limit scratches up and down. The main reason is to avoid accidentally patching the paint to other areas, perhaps during car paint activities. Shake the touch-up pen up and down for more than 30 times to ensure even paint. Then unscrew the cap, take out the paint pen, and scrape off the excess paint at the bottle mouth. Use the tip of the pen to carefully and evenly modify and fill the scratches. First, apply a thin layer and wait for the paint to become slightly monotonous every 5 minutes. Then, operate the second and third coats until the paint surface at the scratch is slightly higher than the surrounding normal paint surface. To achieve better results, grinding paste can also be used to smooth scratches and paint surfaces, increasing the adhesion of the car paint.

3. Paint polishing and polishing: After waiting for 3 days, remove the adhesive tape and investigate that the paint surface is still good. The paint surface is noticeably higher than the surrounding area. After some thought, how about using a blade to cut it open? Take out a single blade, follow the previous process of correcting drawings, try to avoid injuring innocent people, and quietly scrape away some higher paint marks. The results indicate that the paint surface is very soft and brittle, and it is very easy to remove, but some of the paint in the scratches has now fallen off. So, touch up the paint from scratch and wait for another 2 days, this time there's no need for a blade.

Immerse 2000 mesh waterproof sandpaper in soapy water for 20-30 minutes to make it softer and avoid causing significant damage to other original car paint surfaces. Clean up the dust on the surface, fix the sandpaper with a sandpaper pad, and gently polish the paint surface at the scratches with water until the paint surface matches the surrounding height.
