Sorry for not responding sooner Cider, as I said in my IM response I've been a bit tied up.
Yeah, the fishing glue thing works too. So does super glue.
Here's some info:

I use a soldering iron when I'm at home. Let's say that you're repairing 5" Kalins Green Pumpkinseed grubs that the tails are worn, heads are mangled, or have tears from them where the hook cuts through, or just won't stay on the hook. Let's say that you have 2 grubs that are in dire straits ready to toss. Keep them, then use some for spare parts. If you're replacing the tail, take the one with the best body and cut the tail off. If the head end of the body needs repair (won't stay on the hook), insert the hot soldering iron head long into the grub body quickly and melt whatever is there holding the grub upright so that it doesn't spill on you or anything else. This will "weld" the plastic inside the head but leave a big hole. Use the tail as "solder" to fill in holes that either you, the fish or hook made by holding it onto your soldering iron and melt it so that it drops into the hole. You can secure the grub in a fly tying vice if you don't want to risk burning yourself with the hot plastic. Then, heat up the rear of the body and attached the "new" tail from the other grub and you have a near new grub. You can also make your own color combinations this way.
If I'm not making sense or you don't follow me, I can try to take some pics and make a tutorial on this. Might be kinda cool anyway to do...
When I have some add'l time.
