Red Label Penofin was created to meet the demand for an exterior wood finish that outperforms all other transparent stains. The highly penetrating Brazilian Rosewood Oil base from sustainably harvested seeds protects and nourishes wood fibers far deeper than any other stain. With the added mildew protection, the “dark menace” will not attack wood so quickly and helps preserve that freshly-milled look. Ultra Premium Red Label is formulated to provide 99% ultraviolet protection. Penofin Red Label is perfect where rain, wind, snow, or high elevations are encountered. The formula in Red Label results from extensive testing and using the highest quality ingredients. As a result, Ultra Premium Red Label gives longer life to any species of wood.
