Not sure why you need glue. I have always repaired plastics with a lighter. Simply fold the lure where the tear is and heat both sides until they liquify slightly. Then fold back to original shape and hold for about a minute till the plastic cools. For major tears you can do the same thing one little section at a time. Don't worry about minor flame ups just blow them out and continue. I have put Castaic soft-baits that were torn in half back together and then fished them for months without further repair. You can repair some pretty deep holes this way without the drawbacks of glue (hard spots and spots that wont stretch anymore). My .02
