Sorry that was an early morning brain fart. I have no idea where that came from. I just bend the pins and the paint pretty much pops off. Then I scrape them with my thumb nail. When I want them really clean I soak them in acetone then wipe them with a paper towel.
Lots of us have been there. The way I do it is I pour with Teflon pins that I bought from Cadman. I tried the metal and didn't like them. I leave the pins in, paint and cure the jig heads. Then I remove the pins and pop the paint off them. After I have the jig skirted and the eyes on I glue the weed guard in. Some guys remove the pins before they cure the heads.
I use Loctite Super Glue Gel and have not had any problems. Just be sure not to overfill the hole before you put in the wg.
A good thing for molds is a release agent Cadman put me on to Frankfort Arsenal drop out. It corrected the mold issues for me in some of my Poison Tail cavities,
Sometimes I make molds from baits that I buy. That gives them a flat side as they are open pours. I hate using salt so when I want them to have salt I put it on the baits after I pour and the salt only is on the flat side. Maybe that is how they were doing it back in the day.
I go directly to the shop it is only a few miles from where I live. If you want, I can look up the phone number and report back this afternoon sometime.
I have tried several wires and found most of them don't keep their shapes. I have switched to the premade harness from Battlefield Wire Products Inc. They run about $2 per unit.
Check out Bear's Baits, Janns Netcraft, Barlows, Lure parts on line, lure craft, etc. See what starter kits they have. You'll also need a heat source, gloves, and some way to pour your baits.
If you want to save money, don't start.
