Prima Nero is a water-based vinyl, rubber, and plastic protectant and dressing for both interior and exterior surfaces. The appeal of Nero is its finish: it's a concours-look with a matte silkiness on vinyl dashes and plastic trim. Nero leaves tires with a look of newness, adding almost no gloss. If you are looking for the glazed donut shine, Prima Nero is not for you. UV inhibitors help defend against sun damage. Prima Nero is detergent resistant for excellent durability.
