I used a two part casting resin that you can pick up at any hobby shop. Made the molds out of latex using plastic shot glasses as the form. Added a lead insert with eyes and brass tubing to run from the front of the head to the back. Once the resin hardened, removed them from the molds, spun them on a lathe to get a smooth surface, sanded them with an utlra fine finishing paper and used a plastic spray gloss finisher. Added a skirt and voila........invested a lot of time, but had fun, learned a bunch, and now have lures that from a material cost aspect saved me money.
