Bodie Ghost Town Siding & Trim is a proprietary conditioning that is applied to “new” Cedar and reacts to the natural Tannins in the wood. The proprietary conditioning is an accelerant to the natural aging process. Both sunlight and water are needed to activate the process, and the proprietary conditioning is targeted toward “Original Barnwood” replication. No more additional maintenance is recommended, simply letting the Cedar age into its natural beauty is one of the outstanding properties of Bodie Ghost Town Siding & Trim. True Antique or Reclaimed Barnwood is usually a product of Doug Fir, Spruce, etc. none of which possess the natural tannins for exterior application.
