I have heard of ethyl cyanoacrylate glue (e.g., Krazy Glue) mending swimbaits, but I think that the success of the adhesion may depend on the kind of plastic that a particular manufacturer uses in the swimbait. I believe also that some anglers use this glue to keep the front of the swimbait attached to the rear of the leadhead. Also, I think that I would use plenty of scent if I used glue on a swimbait because I do not know if the glue is offensive to fish and, if so, does the glue's odor/taste dissipate quickly in the water.
