a cover for inhibiting corrosion of a metallic object over which the cover is placed . the cover has an inner surface defined by a liquid - permeable layer and an outer surface defined by a liquid - impermeable layer . a moisture - absorbing layer is sandwiched between the liquid - permeable layer and the liquid - impermeable layer . the liquid - permeable layer allows vapor and liquid moisture beneath the cover to be absorbed into the moisture - absorbing layer to reduce the amount of moisture beneath the cover . the liquid - impermeable layer repels environmental liquid moisture , such as rain , sea spray , dew and the like and prevents such moisture from penetrating the cover . a radar - influencing layer and vapor corrosion inhibitors may be included in the cover . a method of protecting an object is also disclosed . the method includes covering a metallic object with cover .
