HI guys. Im new to tackle making and recently purchased my first melting pot and 2 molds. I have a question when it comes to pouring jig heads. Do you spray anything in the mold before pouring the lead into it? I have a pot and 2 molds but no lead. Where’s a good place to get this cheap? I’ve read tire weights aren’t any good. Ill take any scraps you guys have....name your price

As always, thanks for all the help!
