Modern technology in coating metals are spray painting and Electro Deposition Painting (EDP), Electro Deposition Painting lasts longer than the spray painting method due to its electrical mechanism in holding the paint onto the surface of the metal leading to a better quality and lasting piece of work. This method can reduce the amount of paint used while at the same time result in a longer lasting product. Electro Deposition Painting is widely accepted as one of the best methods in coating especially for products with a complex structure. The method results in a high resistance to rusting and the method of EDP uses paint that are non-Lead, Cadmium, Mercury, Hexavalent Chromium which means that it has a low impact to the environment which is used mostly in industries of vehicles, electronic appliances, furniture, and other products that require resistance to rusting.
