This one I think: http://www.georgiacombat.com/CASTOR_OIL.htm CASTOR OIL They prevent the final breakdown with additives: "Unfortunately, the end byproduct of this process is what we refer to as "varnish." So, you can't have everything, but you can come close by running a mixture of castor oil with polyalkylene glycol like Union Carbide's UCON, or their MA 731. This mixture has some synergistic properties, or better properties than either product had alone."
