Carbon parts: to grease or not to grease???

Hello people,
I'm building up a Bianchi scandium frame, and I'm going to use some carbon components for the first time. My question is this:

Do you grease a carbon seatpost? What about the carbon steerer on th
fork, should I put a tiny bit of grease on that before I clamp the ste
(a TTT forgie XL) to it? And if I use carbon bars, should I grease th
collar aswell? I use synthetic white lithium grease

I was shopping for parts in a local retailer the other day and I spotte
a label on a Specialized carbon seatpost that said "Do not grease"
After asking a local mechanic about this, he said he puts atleast a tin
bit of grease on any carbon part. He said he once didn't put grease on
carbon seatpost, and it went in easily during installation. But when i
came time to remove it a some time later, he had to really muscle it t
get it out. So because of that experience he said he always puts atleas
a light film of grease on carbon parts

Maybe manufacturers don't want certain greases used on carbon stuf
because it will deteriorate the coating over time? Have any of you hear
of a carbon part being ruined because of grease? And have you found tha
ungreased carbon parts prone to creaking

Any advise is appreciated

DON't put grease on carbon seatpost. Did put some on mine, and it took some
really husky kids at the LBS to get it out. The grease turns into some kind
of glue as it reacts with the outer finish of the carbon seatpost.

So what to use? greasless produces the same stuck result (you dan't want to
see my alien) . Anti seize? Beeswax, Grant fans? Silicones? Will the
chemists amongst us help us know what's up. Please.

Nope, just the faceplate bolts, use a torque wrench.

Don't grease a carbon seatpost on a carbon frameset, that has a carbon seatpost
insert.

Don't use a carbon seatpost is the (expensive) conclusion I came to.

E.g. EASTON says not to grease a carbon seatpost, in order not
to overtigthen the clamp, which may lead to cracking a seatpost
(i.e. not greased doesn't need that much clamping force).

What types of frame materials are showing the most reaction with a
carbon post?
Both my Ti frames have carbon posts and I worry.
My routine so far includes removal of the post every few weeks,
cleaning it and the inside of the frame tube thoroughly, then
reinstalling. As of yet, I haven't had a stuck carbon post. I also
completely disassemble both my bikes during the winter months for a
complete cleaning and inspection.

Wow, you go to all that trouble just to ride a carbon post?

It only takes a few minutes. I used to do the same with aluminum posts
in steel as well and frequentlt cleaned corrosion, even with them
lubed slightly.
