Generally I don't have any problems with boolit release from ferrous molds after they've been "broken in" (deburred and stuff) but I may be moving to a more humid climate and was wondering if Kroil oil can double as a good rust preventative and mold lube. When I say mold lube, I'm referring to the wear points (sprue plate and alignment pins). I like to cast at a relaxed pace with my pot near 800F. Also, what is used to dissolve Kroil oil?
I was also thinking about using 2-cycle oil to protect and lubricate but I'm not sure what dissolves that stuff either... in case I need to clean the cavities squeaky clean.
Thanks for your input,
