Hey I have an idea. I use this to get bearings of of Stihl trimmer shafts, because they are pressed on so damn tight. I take a can of liquid air, like the ones you use to dust off your PC motherboard, and I hold it upside down and squirt liquid air onto the shaft where the bearing is. The metal contracts enough from the cold that the bearing slides right off. Maybe if you tried to spray the bolt with this stuff it would shrink enough to a)break free from the loctite, and b)loosen the contact between the bolt surface and the head surface. Worth a shot anyway, just watch your fingers, heheh.
