The reason for using the Metal Coatings would be to make something that was not made of metal look as if it were made of metal. For example, a ceramic or plaster object would appear to be made of bronze if the Bronze Metal Coating was applied on it. Another application would be to change one type of metal into a different metal. For example, if you apply the Copper Metal Coating over steel, the steel will appear to be copper. Another popular use is to apply the Iron Metal Coating over iron or steel. This allows you to completely rust the Metal Coating surface without compromising the base metal. Since the coating is an outdoor product, there will be no further disintegration, even outdoors.
