That day when I was driving to work, I noticed a long scratch on my car door and finally understood that 'keying' refers to using sharp objects like keys to scratch the car's surface. This damages the paint, and if not repaired in time, rainwater can seep in and cause rust, potentially requiring the entire door to be replaced at a high cost. When I went to the repair shop, the technician said it would cost over two thousand yuan. Now I always choose parking spots with good surveillance. Actually, such incidents are quite common in daily life—some people intentionally vandalize, or drivers accidentally scrape others' cars. I recommend applying a paint protection film for defense and keeping keys away from the car to develop good habits that can save a lot of trouble. A car is a means of transportation; taking care of it is like protecting your own wallet.

Having worked in an auto repair shop for a long time, I often encounter customers complaining about 'keying' issues, which means scratching the car's surface with hard objects. When deep scratches damage the primer, the repair process is tedious: first sanding, then filling, followed by painting and baking. If not done properly, color mismatch can occur, leaving car owners distressed. For light scratches, applying toothpaste can help reduce visibility, but it's not recommended to try it randomly. I've found that the causes are often parking lot disputes or children playing around. For prevention, installing a car wrap or regular waxing works well. Leaving scratches untreated for a long time increases the risk of metal corrosion, affecting driving safety—prompt treatment is the wise choice. Don't let minor issues turn into major repairs.

When my child was waving the keys around and scratched the neighbor's car, I finally understood what 'cross-scratch' meant. It's essentially accidental damage to a car's exterior. Teaching kids to be responsible is crucial—cars are valuable items and shouldn't be touched carelessly. Similar damage can also be caused by pet collars or bicycle handlebars. Simple prevention: park close to a wall or cover the car with a soft cloth. Educate children promptly to cultivate good habits of taking care of things. Though such incidents may seem minor, repair costs can be significant. Learning basic knowledge can prevent major conflicts.

I came across the phenomenon of 'keying cars' online, where some people scratch cars out of boredom to vent their emotions, but this is disrespectful to others' property. Simply explained: using sharp objects to scratch the car's paint surface. Light scratches can be temporarily fixed with a repair pen, while deeper ones require professional repair. As someone who parks frequently, I suggest staying calm and resolving disputes without impulsiveness; installing alarms or surveillance cameras is effective for prevention. Remember, truly being cool means taking care of your car, not following the crowd in doing foolish things. A simple small act can turn into a safety hazard.
