1. A lineal product comprising:
a composite pultruded substrate having a solid outer surface; and
a multi-layer coating extruded directly onto the solid outer surface of the pultruded substrate, the coating comprising:
a solid extruded base layer comprising a first thermoplastic material extruded onto the solid outer surface, the solid extruded base layer having a base-layer inner surface in intimate contact with the solid outer surface of the composite pultruded substrate and a base-layer outer interface; and
a solid extruded outer layer comprising a second thermoplastic material comprising polymethyl methacrylate extruded onto the first thermoplastic material of the base layer, the solid extruded outer layer having an outer-layer inner interface in intimate contact with the base-layer outer interface and an outer-layer outer surface, wherein the intimate contact between the base-layer outer interface and the outer-layer inner interface forms a solid interface between the solid extruded base layer and the solid extruded outer layer,
wherein the solid extruded outer layer has a hardness of at least 1H pencil hardness.
