greasing up z-axis space grip premium

[heman86]

hi,

after having used the stick for ~50h the z axis isnt as smooth as it was at the beginning so i thought about greasing it up.

has anyone tried it? what grease did you use? is there any "how-to" or video that shows how and what you have to grease up.

thanks.
