Compliance Pivot/Caster Adjuster re-assembly quesiton

I have the entire front suspension off of the car and off for new ball joints. While I was in there I decided to finally take care of the seized caster adjuster on the driver's side. Some thorough PB-Blaster marination and rubber mallet encouragement later, and voila, I can now actually completely align the car once everything's back together.

My question is this: when I re-assemble the caster adjustment bracket onto the compliance pivot assembly should I employ some type of lube or anti-seize, or is this intended to be a "dry" interface?

Pieces in question highlighted below. Thanks in advance for any experience/facts/sources.

Please apply silicone grease to shut out the moisture in order to prevent the caster adjuster from being seized.
Lots of NSX has the same issue and no longer be able to adjust the caster.

It’s not for the same reason but in Japan, some of the owners including myself heard single cracking noise from the compliance pivot when going over the small hump when entering the car park, etc.
At that time, Honda offered the following service under warranty and disassembled the compliance pivot and at the same time, they applied grease at the cup where the pivot arm/body cyl sits.
Even after 22 years, my caster adjuster rotates smoothly unlike many NSX that I tried to adjust the caster during the alignment session.

I borrowed this pivot from another owner and as you can see, over many months/years, because of the moisture entering the metal to metal contact section, it created oxidation and seized the two parts.
In the last photo, you can see where it seized.

It's very rare but exactly the same thing can happen at the camber adjuster bolts inside the lower A-arm bush.
This happened not only with NSX but also on other models such as S2000 as Honda uses metal collar inside the suspension bush where the adjuster bolt is inserted.
Applying silicone grease around the bolt body (but not on the thread) whenever removing suspension bolts will help in preventing seizure.

The cup and pivot arm are locked by the two nuts (caster adjuster locking nut and another lock) and the pivot assy is connected to the upper/lower A-arm through the ball joint so even when the pivot rotates, applying silicone grease has no effect.
In fact, because of this structure, once it’s seized, you have big time trying to release it because any force will be simply absorbed by the ball joints.

Great information. Thanks Kaz!

My caster adjuster was seized on one side and very stiff on the other and, as you mentioned, I've had at one side of the camber adjuster seized in the past (that's also been corrected).
