Etymology: "Overcoated" is simply "overcoat" with the suffix "-ed" attached, turning a noun into an adjective describing something that has been given an overcoat. The base word is itself a compound: "over" meaning above or on top, and "coat" in the sense of a covering layer, so the whole thing literally describes a surface with another layer laid on top of it. The word's wider meaning follows from the noun. Something that is overcoated has had a further layer placed over an existing one, whether that is a protective finish on paint, a glaze on ceramics, or a film on a surface. The sense is therefore a plain, literal description rather than a figurative extension, and the component parts explain it fully.
