For 600 years the Chinese have treated boat timbers with tung oil. Tung oil, was used to waterproof Chinese ships as long ago as the 14th century. The thin, transparent oil penetrates deep into wood pores, forming an almost permanent seal against moisture because it never loses its elasticity. 
Tung Oil is the world's oldest and best wood preservative. 
It was grown in China for many centuries before its introduction 
into Europe and the America, where it is now grown most notably in America.

We recommend Tung Oil instead of linseed oil, varnish, lacquer or shellac preparations for the following reasons:

Tung Oil is easy to work with and protects by penetrating the wood surface, leaving no streaking or brush marks. Tung Oil offers a protective barrier against water, stains, abrasions and wear. Tung Oil will not darken with age, as other finishes will. 

Tung Oil will not mildew - linseed oil will. Linseed oil "bleeds" out too excessively for a satisfactory finish. Tung Oil Finish dries clear to allow the wood's natural beauty to come through. The look is natural, hand-rubbed, classic; perfect for fine furniture. 

The largest application for the oil is paint and varnish, and also wide utilized by soap ,inks, electrical insulators.
