So I am replacing the standard crankset on my Litespeed with a compact crank. I have campy equipment, the old crank is a square taper and the new one is an ultra torque. Is there a specific grease or locktite that I should use when I thread the BB cups into the titanium frame? I've been using Park tools Polylube 1000 for lubing all the fasteners so far, but I am not sure if this would be a problem with dissimilar metals.

Thanks in advance
