cedar requires a UV protector to not turn grey. If you use thompsons water seal it will still grey off. You need to use a product called Penofin (Available at Timbertown - talk to Bigtime) or Skikkens (available at Cedar Shop talk to Cedar Meter).
It is best to oil (finish) all sides so that greying cannot come from the back out. Bigtime and Cedar Meter will have more info.
