Automotive paint is paint used on automobiles for both protective and decorative purposes.Water-based acrylic polyurethane enamel paint is currently the most widely used paint for reasons including reducing paint's environmental impact. Modern automobile paint is applied in several layers, with a total thickness of around 100 µm(0.1mm). Paint application requires preparation and primer steps to ensure proper application. A basecoat is applied after the primer paint is applied. Following this, a clearcoat of paint may be applied that forms a glossy and transparent coating. The clearcoat layer must be able to withstand UV light.
