Penofin Oil Stain exterior wood finishing products on your wood projects to beautify and protect against fading, discoloration, mold and mildew. Penofin transparent exterior finishes were formulated to enhance and protect the natural beauty of wood and to prevent discoloration from the sun’s ultraviolet rays. Penofin resists stains and retards nail bleed. Penofin complies with all national and local air quality regulations.
Penofin Blue has a small odor. This product is easy to apply and absorbs well into the wood. The initial appearance looks pretty good, but not great. The instructions stress wiping the stain after applying to reduce sticky finish. Even though the finish looks OK, who really wants to wipe their entire deck after staining? 14 month weathering results were the worst of anything we tested. Severe failure, graying, color loss and mildew growth were all terrible.
