23-028-152018-12-10. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY. Matte Finish Care And Protection Matte paint is a unique exterior treatment that gives your Fiat 500X a distinctive appearance. Matte finishes are different from other automotive paints and need special care to maintain their appearance. Typical gloss paints use a high gloss clear-coat finish that reflects light and gives a shiny appearance. A matte finish uses a different coating that diffuses light, providing a unique ?flat? finish. Unlike a typical high gloss clear-coat, damage to the matte coating (such as scratches or wear from aggressive cleaning) cannot be polished or buffed out. Once an area is damaged or becomes shiny, the ?flat? appearance cannot be restored.
