no grease, just dry threads and never had a problem in 12 years

For stem bolts I dont bother but if its a larger Ti bolt under high torque into alloy then I do.

galvanic corrosion can set in effectively welding the surfaces together. Don't worry, this is only an issue with bottom brackets which stay put for many months/ years.

My Ti rotor bolts galvanically welded themselves into my hubs, I used copperslip.

Cant get one of the bolts out. :oops:

Yes, it is. Ignore the people trying to save a couple of bucks by doing things incorrectly.

Yes it is required and not just on the threads, particular attention should be given to the underside of the bolt head where it mates against the alloy surface.

Cheap insurance. I use it on all bolts.

Definitely yes... alu and ti together can also result in creaking, the anti sieze/slip will stop that.
