The answer to this question is a little descriptive, as Paint and custom car wrap are two different products.
Paint is a protective coating that is applied to the vehicle. It's a liquid with pigments, solvents, and other chemicals that allow it to adhere to the vehicle's surface. The paint is applied in two ways: spraying or brushing it on. It can also be applied using an airbrush sprayer, allowing for more precise paint application control.
A custom car wrap is a product made of vinyl or plastic material (sometimes called "bubble wrap" or "poly film") that is applied over an existing vehicle's paint job to add new designs or color changes to your car's exterior.
