I am working on a 74 Raleigh International i just acquired. It had a a Shimano fixed cup BB in it that was loose , with both cups beingly only barely tight. The threads appear undamaged but the cups or a sealed BB can rock side to side slightly until seated against BB face. Reading other threads it seems Teflon tape will take up slack in the thread interface. My question is , if I use teflon tape should I use grease, or Anti-seize or install dry?
