I don't remember what kind of wood CDR used for the back stairs—it was something tropical—but it looked really nice when they finished the project. I really regret we didn't finish it sooner. The nine years of weathering did not improve the appearance of wood and my several hours of sanding didn't do enough to remove the weathered wood.
Yesterday, I finally finished applying the Cabot Australian Timber Oil. I like the finish. Too bad I didn't do it sooner. =)
The boards next to the door are covered by a roof overhang so they look the best.
