A car stencil is a template used to create designs or patterns on a car’s surface. It is typically made from a durable material like plastic or cardboard, with cut-out shapes or letters. When placed on the car, the stencil allows you to apply paint or other materials to the exposed areas, creating a precise and consistent design. Car stencils are often used for custom paint jobs, logos, or decorative purposes, making it easier to achieve professional-looking results without freehand painting.
