The fading and oxidation of car paint can be repaired through various methods, such as polishing, glazing, coating, using car wash mud, waxing, and applying painting techniques. In severe cases, repainting may be necessary. When such problems occur with the car paint, mild methods such as waxing and using car wash mud can be chosen; For moderate cases, polishing and glazing may be considered; Heavy coating or repainting is more suitable. Different repair methods have their own characteristics and applicable situations, and car owners can choose reasonably according to their needs to restore the gloss of the car paint.

Polishing is a common repair method, which includes processes such as sandpaper polishing and machine polishing. During operation, different thicknesses of wax should be selected for polishing based on the specific condition of the damaged paint surface. After polishing, it is recommended to apply wax in a timely manner to protect the paint surface, as polishing will thin the car paint to a certain extent, and waxing can provide subsequent protection. However, polishing should not be too frequent, otherwise it will cause irreversible damage to the car paint.

Sealing glaze is achieved by pressing the glaze into the interior of the car paint using a vibration polishing machine, thereby forming a protective layer. The main component of glaze comes from petroleum, which causes significant damage to the paint surface. The maintenance film formed by this method is not resistant to acid and alkali cleaning and is easily damaged. It usually only lasts for 1-3 months, so it may need to be sealed again every two to three months, and this operation generally requires a professional beauty salon to carry out.

Coating is a paint surface care process that is effective but relatively expensive. The film material used is inorganic, which does not damage the car paint. It can also increase the hardness and durability of the paint surface through multi-layer coating, providing more lasting protection for the car paint.

The operation of repairing car wash mud is relatively simple. Firstly, the vehicle body should be washed with clean water to remove surface dirt and grime; Then take out an appropriate amount of car wash mud and knead it into a suitable shape; Spray water on the oxidized paint area, then let the car wash mud slide back and forth in that area, without pressing hard, until there is no feeling of particles; Keep the vehicle moist throughout the entire process; Finally, clean the car body with a clean towel, and then proceed with normal car washing. If the oxidized area of the car paint has not been restored after such treatment, then it is necessary to consider repainting.

Waxing is also a good choice, especially for cases of slight oxidation. After applying wax, shaking the wax to emit light can not only improve the brightness of the paint surface, but also block the contact between the car paint and air, thereby playing an antioxidant role.

The painting technology is based on traditional polishing, using a spray gun to spray specialized products, and then using sponges and towels to correct and wipe, in order to repair the fading and oxidation problems of car paint.

If none of the above methods can effectively restore the oxidation and fading condition of the car paint, then repainting is the last choice. When repainting, it is important to choose a reputable and professional repair shop to ensure the quality and effectiveness of the paint.

In addition, to avoid the problem of paint fading and oxidation caused by sun exposure, sunshades can be placed on the front and rear windshields of the car, or car clothes can be worn on the car, which can protect the paint to a certain extent. In short, when facing the problem of paint fading and oxidation, car owners not only need to understand various repair methods, but also pay attention to daily maintenance and protection of the paint, so as to keep the paint of their cars in good condition.
