Agree with all on the glues, the creep can be a problem with the newer glues - but as has been said before the "heat breakdown" does make it easier to repair and instrument. But when you really get down to it, how in the hell are you going to allow your instrument to reach 200 degrees? (I've made that mistake with a harp, and fixed it, but never again). Two hundred degrees (which can be reached rather quickly in a closed car in the summer sun) would kill your cat, dog or toddler. Are you going to subject your instrument to such temperatures.
I make golf clubs (among other things), and use an epoxy that breaks down at about 220 degrees (but they don't absorb the ambient temperature as quickly as wooden instruments). The choice of the glue comes from the need to break down the joint to replace a broken shaft, and not need to overheat the club head. BTW, I use a "heat gun" that produces 500 degrees or 1200 degrees, but don't use it too closely - so as not to melt the graphite - it is a bit of an art to get it right. Best, Jon
