Bicycle Mechanics - Chainring Fasteners --- Lube?

I will be installing a replacement chainring on an S-Works carbon crank. What is recommended for the threads on the chainring bolt threads?
Lube of some sort or Loc-tite?

A little dab of grease is what I use.
There is not much thread area on those bolts given the forces they are under, so some kind of lubricant is a good idea just to be able to tighten them up properly. It also doesn't hurt to lube them so that they don't freeze up too. Grease is great. So is anti-seize compound. Even Lok-tite functions as a thread lubricant until it sets up, so that is fine too.

I have found grease works best - it keeps the friction between the bolt and nut lower than the friction between the nut and chainring, so the friction between the nut and chainring should be all you need to hold the nut in place while you tighten.
If you use locktite make sure you use the non-permanent type (blue), because if you use anything stronger you may find it impossible to remove the chainrings ever again.

My policy is:
Anything that has a chance of getting frozen, gets a graphite based anti seize paste called Never Seize that I get at a plumbing store. I use this for most of my bike parts, lug nuts on my car, engine bolts that are under severe heat.
For any metal to carbon parts or carbon to carbon parts on a bike, I use a carbon anti seize paste. I use this on my carbon seat post. You can put it on with your fingers or a flux brush.
You don't much of either compound.

I have been in the habit of using loctite on everything except the BB, (where I use anti-seize), but in light of the pain I had getting the last set of loctite'd chainring bolts out, I'm now inclined to go with grease or anti-seize for those.

I agree - if it moves it gets grease, if it doesn't move it gets anti seize.
