I have been using PRO's Soft~Bait Glue for almost 2 years and they are the best on the market. I use it to keep the soft plastic baits on the jigheads. It takes one drop to repair a torn tube or grub, its ordorless, strengthens my knots 100%, and the best part is...it stays soft and flexible!!! I've used LOCTITE & Super Glue before too, but they get hard and stinks in the water. You can even customize your own baits with different colors and baits to catch more fish! BTW...I'm still on that same bottle, because it only takes one drop! Here is the URL:
