Claim 7:
8. A lineal product comprising:
a composite pultruded substrate comprising a fiber-reinforced thermoset resin, the composite pultruded substrate having a solid outer surface; and
a coextruded bilayer coating coextruded directly onto the solid outer surface of the composite pultruded substrate, the coextruded bilayer coating comprising:
a solid extruded base layer comprising a colored thermoplastic material comprising polymethyl methacrylate extruded directly 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 coextruded outer layer comprising a clear thermoplastic material comprising polymethyl methacrylate coextruded onto the first thermoplastic material of the base layer, the solid coextruded outer layer having an outer-layer 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 interface forms a solid interface between the solid extruded base layer and the solid coextruded outer layer,

wherein the solid coextruded outer layer has a hardness of at least 1H pencil hardness.
