Re: Tung oil, right?

Tung oil is often mistaken for linseed or danish oil but is in fact as much a surface coating as a penetrating oil. It is used as an additive to varnish to extend durability and elasticity. Commercial, or volatilised tung oil, as opposed to pure,is fast drying and will build coats on the surface quite rapidly. It is highly water and chemical resistant and dries to a relatively hard surface that resists scratches. Not as tough as varnish or polyurethane but, unlike "goopethane" it is easily repairable.
Good choice for speakers. The durability of the Great WAll of China owes much to the fact that the masonry was coated with tung oil.
