Gentlemen,
I have an older Lyman mold that has lost some of the original finish inside the cavities. I was wondering if I could touch it up with cold blue in order to give a LITTLE (very little) corrosion resistence while it is stored. I oil my molds heavily anyway, but thought this might be a little added protection.
I'm just wondering if the cold blue would come off when the mold is hot, or will effect casting in anyway.
Guys who make your own molds, how do you, or do you finish them?
Thanks
SSB
