It's kind of embarrasing. I pour plastics and my tail is the worst part of my bait :+

I haven't taken the time to actually make a mold yet. I made a temporary mold out of Sculpey. I didn't even cook it. I just spray with pam or put some worm oil in it. Before it cools all the way, I turn the mold over onto a piece of aluminum. That makes both sides of the tail shiny. It's amateur, but it works for now :-)
