Traditionally, industrial color coats have been achieved through the self-explanatory process known as spray painting, where paint is applied in aerosolized form through pump devices at high pressure. In the majority of applications, the paint is delivered via pneumatic-powered tools or machinery to achieve a consistent, even coat along a chosen surface.

Before you can apply a coat of spray paint to a chosen surface, you must clean the metal of oily residue and dirt. You then treat the surface to a wet-blast of roughly 15-20 micrometers. The process continues until you have evenly coated the entire surface with a sufficiently thick layer of paint.
