Corrosionpedia explains Temporary Coating
Temporary coatings are often applied on metallic surfaces that are prone to corrosion to reduce the influence of corrosion-causing environments and substances. Temporary coatings can be used in situations where long-term permanent coating options are unavailable or cost prohibitive. They are also applied to metal parts prior to being transported or shipped with the intention of preventing damage or corrosion to the component before it can serve its intended purpose.
