Some info on loctite:
Loctite Blue 242 is for screws that may need to be removed.
It's used for scope bases and rings, grip screws, etc.
It's purpose is to prevent screws from vibrating loose, yet still allow them to be easily removed with standard tools.
Loctite Red is a permanent bonder for screws that will not normally be removed.
This is used for 1911 grip screw bushings to prevent them from coming out with the grip screw, and anywhere else you want something to be firmly bonded in place, and you don't plan on removing it.
To remove parts bonded with Red, you need to use heat and heavy-duty tools.
Loctite Black, also called Loctite "Black MAX" is a "super glue" mixed with rubbery bonders.
This is used to bond ribs and sights on shotgun barrels, and is apparently some good stuff.
The rubbery bonders cushion vibration and prevent the parts from coming off.
It's primarily a bonder used to "glue" parts on something. It's used in the automotive industry to bond handles and knobs in cars.
Loctite Green is a very thin consistency and is used to secure screws that are already in place.
The thin consistency allows the agent to "wick" into the threads.
There are two types of Loc-Tite Green
Loc-Tite green thread retainer #29000 is used like Blue 242 but you can loosen and retighten screws without having to reapply the compound.
This stuff is good for screws such as grip panel screws that you may want to eventually take out for access to internal parts for cleaning etc.
Loc-Tite #609 is a retaining compound that is used for permanently anchoring press fit bushings or any componenet that is intended to be more or less permanently anchored in place.
It requires more heat and force to remove than Loc-Tite red.
All you could want on using threadlockers and retaining compounds.
