How do you re-grease a loose polarizer filter?

Brand new polarizer spins way too easily in it's mount. It is used on a
movie camera and it slowly revolves while shooting and the outcome is
getting annoying real quick.

Short of using a rubber band to hold it still, has anyone ever pulled the
rings apart and put some thicker silicon grease on them so it would work
smoother? If so, how did you separate them?

I got the glass and retaining ring out but the thing (Hoyo brand) appears to
be snapped together somehow.

Try a de-greaser (to remove some/all of the lubricant that is in the
ring). With the glass out of the way, this should be a simple task.

You can get commercial stuff like 'Gunk', but thinners used for
white-out might do the trick too.

Disclaimer: I've never had to do this.
