ABSTRACT
There are two facets to metal coatings — coatings on metal substrates, and metals as coatings on any substrates. The latter can be lumped together in a one-word category called “metallizing,” which is done in many ways. The former, coatings on metal substrates, generally are thought of as paint-type materials but may include waxes, inks, and other coatings. The two topics will be dealt with separately, beginning with metallization, as those metal surfaces are often painted or coated for protection, as well.
