Any purposeful damage or defacement of property without the owner's permission is considered vandalism by the Federal Bureau of Investigation. If your car is vandalised with eggs, it's important to understand how the substance affects car paint.
Eggs can damage car paint. Car paint that is exposed to raw egg can sustain permanent damage after only about two hours of exposure.
The sulphur and amino acids in eggs harm car paint. After sitting on the clear coat and paint of your vehicle, eggs actually eat and etch the paint away. Heat can accelerate this process and cause further damage.
The longer the car paint is exposed to egg, the more damage will occur. If only the clear coat is etched, refinishing is possible. If the egg penetrates to the paint coat, a new paint job is a possibility.
