A stain/topcoat system for non-porous thermoset and/or thermoplastic articles comprises a pigmented stain having substantially only a single binder resin which promotes adherence of a topcoat, and a topcoat which is an aqueous dispersion of a film forming polymer and a curable organopolysiloxane microemulsion. The topcoat displays exceptional adhesion and weatherability to pigmented stained surfaces.
