What do you do to your molds after the casting session?
Sorry if this is a repost. I tried searching but didn't seem to find anything.
I just started casting. I have a Lyman 358665 2 cavity mold. I casted my first boolets tonight. I was wondering what you guys do to preserve your molds after your casting session. The mold is hot and as it cools I would think a small amount of moisture would develop in the cavities which could lead to rust and other undiserable situations.
I've read here before lots of guys saying they don't put anything in their mold cavities.
Don't want to ruin my molds with oil or anything that may damage them, but surely do not want them to rust!!
Thanks in advance!
