A clear coat is a transparent layer of paint applied over a colored base coat on vehicles and other surfaces. Its primary purpose is to protect the underlying paint from damage caused by UV rays, scratches, and environmental contaminants. Clear coats enhance the shine and depth of the color, giving the surface a polished appearance. Typically made from polyurethane or acrylic, clear coats can be applied using spray guns or brushes. They come in various finishes, including glossy and matte. Proper application and maintenance of a clear coat can significantly extend the life of the paint job on cars, furniture, and other items.
