Dale,
JB works very well if you're careful.
I dry fit the guard so the last 1/16th" to 1/8" will be a pressure fit to the blade. use a wrap of tape in front of where the guard will seat, within 1/8". Coat the whole front of the guard with anything waxy...Chapstick works and smells good. Lightly and evenly coat the tang and inside of the guard slot, it won't take much JB. Press on your guard and go do something constructive for a half hour or so. You'll be tempted to screw around with it.....but leave it alone . When the JB that bulldozed in front of the guard feels rubbery , then remove the excess with a tooth pick or anything softer than your blade or guard. Clean the area with a Q-tip and acetone. Only remove the tape after you're sure you're completely done. Remember that if your guard fit is sloppy, you'll wind up with a grey line between the guard and blade. You should'nt see any JB at all after clean up. Use common sense and Good luck.
