How to Repair Severe Car Paint Oxidation?
2 Answers
Repainting is a common method to restore the gloss of car paint. Forming a wax film on the surface of the car paint can inhibit the oxidation effect of harmful external components on the car paint. Glazing can increase the strength of the car paint, prevent fine scratches caused by wind and sand hitting the car body, and resist high temperatures and UV rays. Like glazing, coating itself is not oxidized by external factors.
I just dealt with my car's paint oxidation issue last month. The car had been parked outdoors for too long, causing the paint surface to become hazy and whitish. The treatment method was to first wash the car thoroughly using a neutral car wash solution to scrub the body clean and rinse off dust and impurities. Then, for areas with severe oxidation, I used polishing compound with a soft cloth to manually polish, gently wiping to remove the oxidized surface layer. For large areas or deep oxidation, 2000-grit wet sandpaper or an electric polisher is needed for deeper treatment to avoid scratching the primer. After polishing, I applied a car-specific paint restoration polish to restore the shine, followed immediately by a UV-protective sealant wax to prevent re-oxidation. The whole process requires a lot of patience, and it's best to work in a shaded area. I recommend seeking a professional auto repair shop for severe cases—they have better equipment and can also check the body for rust spots to prevent corrosion. Don't slack off in daily maintenance; applying wax every quarter can effectively prevent oxidation damage.
