Why Do Black Cars Show White Scratches?
2 Answers
Scratches damage the car's primer, resulting in white marks. Here are specific methods to avoid car scratches: 1. Drive cautiously: Follow traffic rules and maintain order while driving. Avoid forcing lane changes or squeezing through crowded areas during traffic jams. Patience helps protect your car from damage. 2. Choose parking spots wisely: Avoid parking in open areas where children might scratch the car. Also, try not to park in tight spaces to prevent other vehicles from scratching yours when maneuvering. If possible, consider purchasing a car cover to protect your vehicle from scratches.
When white marks appear on my black car after scratches, it's mainly because the paint layers have been scraped away by hard objects. A typical car paint system consists of the outermost clear coat layer, the middle black color coat layer, and the bottom primer or metal body. If the scratch is deep, it penetrates the black paint to reveal the grayish-white primer – which manufacturers typically use as a base to enhance adhesion. For shallower scratches, when the clear coat is damaged, the surface becomes rough and reflects light differently, appearing white due to accumulated dust or moisture. Daily scratches from tree branches or keys can cause this situation. It's recommended to park away from cluttered areas and regularly maintain the paint with wax to minimize such occurrences.
