The way of powder coating works is that powder of a certain color is sprayed onto the metal surface, which holds an electrical charge. The charge causes the powder to adhere to the surface, and it is baked on once the spraying is done.
Antique is a special kind of powder paint with a special component in the composition. They are designed to mimic antiques or rarities that carry the spirit of the past. The objects covered with such paint are reminiscent of the products of ancient times. The coating has a slightly rough structure.
