Hogy came out with a rigging glue that is custom made to bond soft plastics to metal. The process works in about 10 minutes and works with every I have tried so far. I even used it fix a hollow body frog.
The process is quite simple. Make sure your surface is not wet, dab some glue on it and quickly make the contact. Wait for about 10-30 seconds and you are good to go.
They are available at Hogy lures at about $10 and will last your 6 moths to a year depending how often you fish.
