A glossy finish is a type of coating that is applied to a surface to give it a shiny, reflective look. The two most common types of glossy finishes are enamels and sheens. Enamels are a type of paint that is made up of a combination of resins, oils, and pigments. They are usually used on metal surfaces and provide a hard, glossy finish. Sheens are a type of paint that is made up of a combination of resins and pigments. They are usually used on wood surfaces and provide a softer, more subtle glossy finish.
