Only thing I use is a drop of blue loktite on areas I don’t want moving, but still want the ability to loosen if needed, like optics.
I have found that while blue works, I prefer the wicking grade green. Medium strength. It holds but I can get it apart. I can also clean it off easier. If a customer wants it on, and for it to never come off, high strength red or rock set. Hahhahahaa
I will use red for #6 screws on a bolt gun rail when it is a magnum.
Use green for #8 screws, same application
I’ll have to look at the green.
