Unique blend of penetrating oil & varnish hardens in the wood, not on the wood. Watco Danish Oil penetrates deep into wood pores to protect from within and to enhance the natural look and feel of the wood. It creates the rich, warm glow of a traditional hand-rubbed finish. Many projects can be completed in less than an hour - simply brush or wipe on and wipe off. Watco Danish Oil is the choice of fine woodworkers and novices alike. Indoor use only (Not recommended for Floors)
