How to Deal with and Repair Cracked Car Paint?
2 Answers
Sand the cracked paint area until a complete and smooth surface is exposed, then repaint. Regular waxing and frequent maintenance can alleviate or even prevent this situation. If the car paint has slight fading or loss of gloss, apply a coat of wax. For severe fading or loss of gloss, repaint the car. Paint oxidation can be treated through grinding and polishing. By grinding and polishing, the oxidized layer of paint is removed, allowing the vehicle to regain its luster and return to its original, new-car condition.
As an ordinary person who has loved cars for many years, I've noticed that paint cracking is quite common, especially in older cars exposed to sunlight for too long. The treatment involves several steps: First, wash the cracked area with soapy water, dry it, then gently sand off loose paint flakes with fine sandpaper—don’t press too hard to avoid damaging the primer. Next, apply a professional primer, wait for it to dry, then coat it with matching color paint, and finally polish it smooth. If the cracks are deep or cover a large area, DIY repairs may yield poor results, so it’s best to visit a reliable repair shop for a full respray of the affected panel. Prevention is crucial—regular waxing to block UV rays, parking in underground garages to avoid direct sunlight, and not underestimating these habits can extend your car’s paint life by five or six years. Also, avoid using corrosive cleaners during washing to prevent further cracking.
