What causes large areas of paint peeling on the car hood?

[Almeida]

Paint fading: Oil fumes and pollutants in the atmosphere are the main causes of car paint fading and discoloration. Fading is different from oxidation, as it results in uneven color differences on the car paint when it occurs. Paint oxidation: Prolonged exposure to the sun's ultraviolet rays can cause excessive dispersion of the oil content in the car paint. Both the brightness and depth of the paint are significantly reduced, causing the paint to gradually turn white and form an oxidation layer, thereby shortening the lifespan of the car paint. Solutions are as follows: 1. Waxing: If the car paint's loss of gloss and fading is relatively mild, you can apply wax to the car. 2. Repainting: If the car paint's loss of gloss and fading is severe, then the car should be repainted to improve overall aesthetics and enhance its protective capabilities. 3. Polishing: Paint oxidation can be treated through grinding and polishing.
