Vantablack was originally developed for use in "satellite-based blackbody calibration systems" that must mean something to someone. However, it is also used for other applications, including architecture, and can be cleverly used to achieve visual effects when applied to a three-dimensional object.
The substance can make objects look two-dimensional, smaller than they are. or helping them to become completely invisible to the naked eye. When used as a varnish, Vantablack is generally unsuitable for vehicle paints because virtually all design details and highlights are hidden. And some of you will be far ahead of us here when we wonder why BMW painted not just the grill, but everything on the X6.
