Generally you must stir a can of paint before you use it.. is paint miscible or immiscible? explain

Paint is immiscible because the layer that forms on top of settled paint is a substance which cannot dissolve with the rest of the paint.  Stirring the paint is only temporarily in effort to form an even and thoroughly mixed solution by physically mixing the separate molecules of the solution.  However, for it to be miscible, it the solution has to be evenly distributed (chemically) on a molecular level as to not separate when left for a lengthy period of time.
