Funny thing. When this topic came up a while ago I had my punch set out and was going to give it a try by pouring a thin coat of plastic on a mold's backside. Just never got to it and put the punches away eventually.
Eyes and I have a limited association. I only use eyes or put eyes on baits or heads that I am taking pictures of. Personally none of the baits I fish with or jig heads I carry to fish with have eyes. And honestly, the Chinese have eyes for so little cost that look super its hard to not just use them for what I need.
How are you attaching these poured eyes?
