Gentlemen,
I've read a few times on here about people using spray graphite on top of mold blocks as a lube. I think I'd like to try it. Other than ordering it from a casting/reloading supplier such as midway, where can I obtain spray graphite? Hopefully locally. I understand that it's a lubricant? What is it's primary use? I thought maybe it was an automotive item, but a call to 2 different auto parts stores turned up empty.
Thanks for any help.
