I've got a fiberglass handled 8lb maul that I've had for a few years that has been pretty good, but the head is starting to get a little loose. When I look at the top of it I can see some of the plastic casing that holds the head on is starting to crumble away. Can I do anything to prolong its life? Maybe some serious caulk in there to minimize the wiggling and crumbling? And after the head eventually does come off, have people had luck putting new handles on, or do you just use your old head as a wedge and go get that new purty maul you've been eyeing? ;-P
