Of course! Superlube! I just bought a big tub of it for my telescope bearing upgrade.
Yes, saw your post on FB. Chain was inspected two years ago while replacing helm breaks, also a good thing to keep eyes on, they do wear though not as risky as fractured link.
It never ends does it?
P.S. contrary to Edson standard recommendations to completely pull the cables (I had a conversation with them at the Newport Boat show in 2017 about this) the cables CAN be inspected without pulling them. It takes two people, patients, a headset for communication and a bit of contortion but moving the helm slowly in each direction and observing as well as running a microfiber cloth along it at key points during the move will reveal any minor snags in the strands. Key points being the full travel at any turns as well as the ends at both the quadrant and the pedestal.
On my boat there is only one location I could not get to the complete travel and that is where it passes under the aft water tank to the quadrant. Being a straight run and never rotated or turned it is a very low risk section. However it is not a difficult task disconnecting the quadrant end and pulling that through to do the inspection.
I am fairly confident Everywhere else the cable can be inspected through its full travel unless it is sections completely sheathed which are are all straight runs as well and well protected and, being properly greased, at very low risk. Any portion that does enter the sheaths can be inspected as it enters or exits as the helm is slowly turned.
We spent a couple hours on this task after the convention and actually fount the quadrant clamp had slipped at some past life so adjusted that but the cables were in very good condition. Took the opportunity to grease all turn blocks and the quadrant as well.
