This Ultra Premium Red Label Penofin wood stain was created to meet the demand for an exterior wood finish that outperforms all other transparent wood 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 easily, and helps preserve that freshly-milled look. Penofin Ultra Premium Red Label wood stain is perfect where rain, wind, snow, or high elevations are encountered. The formula in Ultra Premium Red Label wood stain is the result of extensive testing, and the use of the highest quality ingredients. Penofin wins the “Battle Of The Stains” penetration tests over all competitors, and gives longer life to wood of any species. Easy to apply and simple to maintain.
