The red loctite is designed to let go when you heat it up to around 300 degrees Fahrenheit. I use a real small propane torch or a heat gun. Watch the back ground. Wrap a wet rag around where your working if plastic is close.
I've used tons of red over the years. I have hardly ever used blue. And yes, if you use too much, it can be re-liquified and fully released, although I've rarely had to resort to heat for disassembly.
The key to using red on small screws in magnesium is all in the amount you apply. I have typically used the big bottles with the removable nipple. When I remove the cap there's usually enough around the base of that nipple to do 2 or 3 screws. I just rub the screw on the puddle of Loctite. A full drop on an 10-32 screw like used on a Super 2 starter housing is too much. If I was dealing with a hole with marginal threads, like a self-tapping screw had taken out most of the threads, I would use a little extra and back off on the tightening torque a bit. Next time you take it out, it might be due for a Helicoil but the thread locker bought us one more cycle.
Any mag case XL or Super 2 that went through my shop since the mid-80's got red Loctite on the engine mount screws, starter housing screws and handlebar screws. They never came loose and I never had trouble getting them back out for further service.
So to each their own. If blue is your preference, more power to you. Just don't be afraid of red because it's "permanent" because it's not. Properly used, it's very remarkable stuff and goes a long way. A bottle of red lasts a LONG time.
