Has anyone use Armour wood found at Lowes? I need to make some porch columns and the wood looks like it would work well. It claims to have a 30-year warranty against rot and the boards are knot free and straight. I was going to go with pvc pre-made post but the style just does not fit my old house. The Armour wood is not cheep, it will come out to about $100 per post just for the boards.
