sunroof maintenance?

[schulz@tif623.ed.ray.com (Peter Schulz)]

Now that the Coupe Q has passed 80k miles, I have been wondering what to do to keep the sunroof mechanism in good working order.

I've looked at Bentley, and the owner's manuals, but could not find anything related to sunroof maintenance.

I assume that the rails should be cleaned periodically and lubricated, however should I use a silicone lubricant, or one such as lithium grease.

Do any of the long-term Audi owners have a preference????
