The LocTited knife is not labeled as to the grade of the glue, you have to discover it with your bit.
It doesn't matter. You apply about 250C heat to the fastener. If the fastener is too hard to unscrew, without breaking your bit in the process, apply more heat and retry. If the fastener is still too tight bump the heat up to about 300C.
I use a Hot-Air Rework Station that can heat the fastener without leaving a mark. You can buy a decent rework station nowadays for $60 or so. I just checked one place and they have a Rework Station & Soldering Iron combo unit for less than $90.
I also use Kapton tape to protect the scales.
