Re: O Ring Lubrication
One thing to think about, is on light's that you have to screw one part into another agaisnt a battery or resistive bumper, like a o-ring or foam pad, after a few times of that you have eliminated a great deal of the lube put on the threads because as the thread meet's the resistence no longer will it stay "centered" moving the "needle" as it would against one side of the "groove" of the thread and chasing out the lube from first one side, then the other.
(i have tested this myself outta curiousity with a strong mag scope to see how and if it migrate's, it does, and with much less use then one would think)
I find considerably better and visable results by using a conductive film like caig product's that will form a harder layer and take more time to loose there effectiveness.and since it's a strong film you can lube over it and still gain most of it's affect.(imho of course) VDG
