Hey Marty,
Short answer: nope!
Long answer: In the presence of an electrolyte like salt water dissimilar materials can create an anode/cathode relationship which results in corrosion of the anode. Aside from the nature of the electrolyte, the rate of corrosion is dependent on the difference in nobility of each material as well as the difference in surface area between the anode and cathode.
This means a low nobility metal like aluminum will corrode when in direct contact with a high nobility material like carbon. The corrosion reaction happens faster if the aluminum component is smaller than the carbon part. Since stainless steel is high in nobility there isn't a risk of corrosion even with small parts:

Corrosion in aluminum can be mitigated with surface treatments like anodization and insulating the connection with non-conductive materials like plastic or fiberglass. The surface area relationship explains why scratches through the anodized layer of an aluminum part will corrode very quickly in salt water when connected to a carbon or stainless steel component.
This effect influenced our decision to select stainless steel for the front portion of the fuselage, however, the driving factor was its high strength and stiffness. These material properties allowed us to downsize the fuselage thickness as much as possible. We've found this has a significant affect on efficiency range which is our primary design focus.
