Penofin redwood all heart brings the rich, dark, mahogany-red color with ever changing velvety sheen to any type of redwood. 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 that any other stain. With the added mildew protection the "dark menace" will not attack wood so easily and helps preserve that freshly-milled look. Ultra premium is formulated to provide 99% UV protection. Penofin red label is perfect where rain, wind, snow or high elevations are encountered. The formula in red label is the result of extensive testing and the use of the highest quality ingredients. Ultra premium red label gives longer life to wood of any species.
