What would happen if you guessed wrong and messed up the screws trying to get them out?
Question? What question? Simply stating my opinion like you. Right? I simply use a soldering gun on the head of the fastener for a minute, just in case it feels tight. No brute force and no chance of buggering up the screw head. In case you don't know, the heat liquifies lock-tite, its not a rust locked bolt that heat may loosen but chemical hold. It feels like it was greased when you loosen it up with a little heat. I even found the blue to be "stubborn" at times. Is this a real comment...? Or just trying to be the smartest guy in the room?
You seem to have forgotten what you wrote, so look above. You asked a silly question, thus my comment.
"Guessing wrong" on what kind of loctite doesn't cause anyone to mess up the fasteners. That's because anyone with sense will stop torquing on them if the screw isn't coming out with reasonable effort. And using heat is totally unnecessary most of the time, like this one on the Icon; even with tons of loctite on the screws in question, they came out easily. I suggest you purchase some quality torx and hex bits if you don't already have some. They bite into the screw and don't strip heads unless you are totally hamfisted.
