I needed to clarify a couple things before responding to this. Technically, galvanic corrosion shouldn't be a problem with an anodized cup. You need an actively corroding material for galvanic corrosion to occur, and one of the reasons to anodize aluminum is to ward off that. That said, provided you use a grease plays nice with carbon fiber, it's a sound idea to install with a thin film of something. Aside from an extra layer of potential protection against the elements it also helps the pieces squeeze together nicely.
