Car's paint is a protective layer applied to the exterior of a vehicle. It serves multiple purposes, including enhancing the car's appearance and protecting the underlying metal from rust and corrosion. The paint is typically made up of several layers, including a primer, base coat, and clear coat, each contributing to durability and shine. The color and finish of a car's paint can vary widely, with options ranging from matte to glossy. Different types of paint, such as metallic or pearlescent, can create unique visual effects. Regular maintenance, like washing and waxing, helps preserve the paint's quality and longevity.
