Etymology: "Rustings" is the plural of "rusting," which is a noun form of the verb "rust," so it refers to instances of the process itself. The underlying word "rust" traces back to Old English "rēst," which is related to words in other Germanic languages meaning the same reddish oxide that forms on iron. The plural form simply treats each occurrence or patch of that process as countable.
