We live in a 100+ year old home in Zone 4A. Porch is 12 x 38 and covered. It has been replaced many times but piecemeal by previous owners and now begs complete replacement of porch deck. We would like ti find composite matieral that would mimic the 21/2″ tongue and groove boards used presently. We would need to either stain or paint in dark grey.

Suggestions?????
