The bench arrived "Curb Side" in good condition. After the wax coat disappears (probably after two month in the full sun), we will clean the bench and apply a Honey tone Semco sealer to make sure it's well protected.
I know you can leave teak outdoors untreated but my wife doesn't like the patina color and I don't mind to put in the work. I watched a Semco video on You Tube and applying the sealer was fairly easy. Just make sure the teak is clean and dry before you apply the coat! I did the same thing with an other teak bench we bought two years ago and it helps to preserve the teak.
