A friend who makes furniture gave me a pill bottle sample of his Gorilla Glue to try. I used a single paint brush bristle to push the glue into a cracked Mauser stock while I flexed the crack open, then wiped a small bit over the whole crackline. After it dried (I was refinishing the stock anyway) I sanded it smooth and now can't hardly find where it was. Also used G-Glue to fit a small nut to the inside of a pistol grip panel for a set of mesquite grips I made for my RSB. The stuff seems stronger than any other epoxy I've used. Pricey, too, but worth it....
