       2 . The lineal product of  claim 1 , wherein the substrate includes a composite pultrusion. 
   
   
       3 . The lineal product of  claim 1 , wherein the base layer includes a dark colored thermoplastic. 
   
   
       4 . The lineal product of  claim 1 , wherein the second layer includes a clear thermoplastic. 
   
   
       5 . The lineal product of  claim 4 , wherein the second layer has a hardness of at least 2H pencil hardness. 
   
   
       6 . The lineal product of  claim 4 , wherein the second layer has a hardness of at least 3H pencil hardness. 
   
   
       7 . The lineal product of  claim 4 , wherein the second layer has a hardness of at least 4H pencil hardness. 
   
   
       8 . The lineal product of  claim 4 , wherein the second layer has a hardness of at least 5H pencil hardness. 
   
   
       9 . The lineal product of  claim 1 , wherein the second layer includes a plurality of micro-beads. 
   
   
       10 . A lineal product comprising:
 a composite pultruded substrate having an outer surface;   a dark colored thermoplastic base layer applied to the outer surface; and   a clear thermoplastic outer layer applied over at least a portion of the base layer, the second layer having a hardness of at least 4H pencil hardness.   
   
   
       11 . The lineal product of  claim 10 , wherein the second layer has a hardness of at least 5H pencil hardness. 
   
   
       12 . The lineal product of  claim 10 , wherein the second layer includes a plurality of micro-beads. 
   
   
       13 . A lineal product comprising:
 a composite pultruded substrate having an outer surface;   a dark colored thermoplastic base layer applied to the outer surface; and   a clear thermoplastic outer layer applied over at least a portion of the base layer, the second layer having a hardness of at least 1H pencil hardness, wherein the second layer includes a plurality of micro-beads.   
   
   
       14 . The lineal product of  claim 13 , wherein the micro-beads are in the second layer at a density of about 10% or less. 
   
   
       15 . The lineal product of  claim 13 , wherein the micro-beads have a size of about 10 microns to about 30 microns. 
   
   
       16 . The lineal product of  claim 13 , wherein the second layer has a hardness of at least 4H pencil hardness. 
   
   
       17 . The lineal product of  claim 13 , wherein the second layer has a hardness of at least 5H pencil hardness. 
   
   
       18 . A method comprising:
 extruding a first, base thermoplastic layer over a pultruded substrate; and   extruding a second, outer thermoplastic layer over the first layer, wherein the second, outer layer has a hardness of at least 1H pencil hardness.   
   
   
       19 . The method of  claim 18 , wherein the second, outer layer includes a clear thermoplastic and has a hardness of at least 4H pencil hardness. 
   
   
       20 . The method of  claim 10 , wherein the second layer includes a plurality of micro-beads.
