Once you get familiar with with how this works, then it's easier to strategize how and when to use it.  It's very messy to work with and takes a long while to set up.  I've used GG (and other brands of the same type of glue - which, incidentally, seem to be identical to the point that I don't really have a preference) for countless things over the years:  I repaired the broken frame of a Nordictrack skier that developed a crack (I glued the crack and clampled it, as well as glueing and screwing a piece of wood to the side, along the crack and a few inches beyond on either side), put a kickboard on the screen door of our front door which is starting to deteriorate at the lower corner, built a small playhouse ladder, and about a million other things I can't recall.
