Press fit BB, lube, dry or Loctite?

My PF30/carbon frame interface is fitted with a little dry PTFE spray. Never creaked.

Dry Ptfe - good call. Carbon/graphite powder would work too - I use that on locks…standard dry lubricant. Doesn’t displace as grease does.

Even some chalk dust (puncture outfit anyone?)

Ah South Downs - our experience that unlike graphite dry lubricant, chalk dust can CAUSE creaking - eg saddle rail and clamp interface.
