Who would ever think it's a good idea to use Loctite on crank bolts?
If the crank is pressed on totally dry and a heavy press, it may not loosen from riding alone. But I'll grant you, I hadn't thought of that when first mechanicing in my youth.
I didn't mean my comment as Loctite on crank spindle bolts, just as a general reference to heat as an aid in loosening things. However, I have seen chainring bolts Loctited (blue) from the factory. I've seen so many instances of snapped small screws that had been Loctited (usually with red), the person totally unaware that a little heat would have prevented that. Loctite (and other threadlocker) website lists softening temp for each type.
