if you pull the wire out right away, you don't need release agent.
for the belly weights i just hold a tire weight over the hole and melt it with a propane torch. the molten lead drips right in the hole. when it cools i give it a tap and it comes right out. then i epoxy the perfect fit weight back in its hole.
