Vinnie's Dark Ultra Penetrating Oil is a natural, solvent-free and non-toxic, hardwax oil consisting of several different solvent free and cold-pressed oils with different deep penetrating properties. A combination of different waxes that penetrate deep into surface create a strong water-repellent effect and unmatched surface protection.  Vinnie's Dark Ultra Penetrating Oil is specially designed for surfaces that are exposed to heavy wear and penetrate extra deep into the wood. For very exposed surfaces, a layer of Vinnie's Wax on top is recommended. The combination offers as good protection as possible with non toxic products. Our Ultra Penetrating Oil leaves a matte finish on wood or satin finish if complimented with universal or wax. Vinnie's Dark Ultra Penetrating Oil surface treatment also delivers a dark rustic look to your untreated wood. Smell of eucalyptus and cedarwood. Vinnie's Oil makes your wood durable and a jar lasts for a large area.
