Grease is a very tricky thing.  You can change the entire "feel" of the lens with the wrong type, or too little or too much.

You may need to disassembly the lens mount further to get sufficient access to the helical threads.  And if you make the
mistake of separating the helical, you may have to spend a long time to get the correct helical
threads to engage - it is a multiple-start helical.

If you heed those warnings and are still brave enough to proceed, then proceed carefully.

I use a mix of Fargo light helical grease diluted with shutter oil, to get the right feel.

good luck

I've got the lense in half, so the focus section is seperate from the optical section. Just wondering how i should about it from here and what grease i shouls use?
