Black Finish polish of black color, as the name implies, was developed to enliven the shine in dark colors, especially in blacks, or for application at the end of the polishing process, to reinforce the shine. It can be applied to the entire car at once, unlike other competing products, which advise the application of this type of product by sections. Very easy to use: Apply the product to the entire vehicle, let it dry and then wipe with a clean, dry microfiber cloth.
