Installed this piece on an exterior south facing wall.  First of all,the style and design of this piece is fantastic and exactly what I was looking for.  Light weight but solid.  The only issue I'm having is that after hanging outside for three months the paint has faded significantly, so much so that it is starting to turn white.  If the fading continues to get worse I'll have to spray paint it with a proper exterior paint, which should not take long at all to do.  Still love this piece though.
