Due to friction during use and improper daily care, slight scratches appear on the car paint surface without exposing the primer. Generally, professional polishing methods can be used to remove them. Static electricity has a strong adsorption capacity for dust, oil stains, and chemical dust, forming a hard traffic film. This can easily cause oxidation and corrosion of the paint surface, which can be treated with grinding and polishing. The naked eye can observe phenomena such as dull, whitish, and lackluster car paint. Severe oxidation can be treated with grinding and polishing. Etching marks are surface abrasions. Insects, bird droppings, tree sap, tar, and asphalt can all cause etching marks. Only very slight ones can be resolved with grinding and polishing.
I've driven several cars before and encountered issues with mismatched door colors, which are often due to replaced parts or poor paint jobs. Check the insurance records for any accident repairs. If it's indeed a paint issue, have a professional repair shop respray it using a color matching machine—costs start from 500 yuan, don't skimp on this. For uneven aging caused by oxidation, try polishing with car wash wax, and remember to use the same brand of polish. Park in the shade to avoid prolonged sun exposure, which helps slow down paint fading—maintaining consistency is key. Significant color differences across the body can affect resale value, so it's best to address the issue early.
I've been repairing cars for many years, and dealing with door color mismatches is common after door replacements or partial repairs with inaccurate color matching. Color discrepancies are often caused by uneven paint layer thickness or UV exposure. It's recommended to visit a shop with painting experience for color scanning to match the original vehicle color code; sometimes only a small area needs touch-up, which is cost-effective. Ensure the use of original paint materials to reduce fading risks, and also check if door hinge deformation causes gaps leading to color differences. For prevention, regular waxing to protect the paint surface can extend its uniform lifespan.
