Armstrong-Clark Redwood Tone Transparent Oil-Based Exterior Wood Stain enhances the natural grain of softwood while adding color and exterior protection. Penetrating conditioning oils help replenish oils lost from the wood, while drying oils remain near the surface to create a dry-to-the-touch barrier. The transparent finish makes the wood grain stand out and is suitable for decks, fences, siding, logs and other exterior softwood projects.
