i use original Blue , red (high stress places) and green Loctite (drivetrain). blue and red loctite can be loosened easily with a good hexdriver (I use Wera ones for this)

Before AP screws I bent and stripped just too many screws (12.9 grade black oxide), not a single Ap screw stripped.

Sometimes it's a bad thread in the hole that leads to stripped screw (had this issue with FLM chassis braces and on friends GA bulkheads but not on G3)
