Copper Slip or normal grease for the bottom bracket threads and seat tube of a titanium frame?

I have watched a few build videos recently on YouTube and grease seems to be used instead of copper slip.

I use ti-prep grease.

Copper Slip / Ti Prep

Copper Slip has worked fine for me for 20years of Ti bikes with aluminium and steel BBs.

Deffo copper slip or Ti-prep. Normal grease won’t protect from galvanic corrosion.

What they said.

Copper for bb shell and seattube and raw ti bolts, but I just use mobil xhp222 grease with my colour anodised ti bolts, controversial.

Any differing metals- copper slip.

Ive been using copper slip. I just thought I’d make sure because all these chaps building bikes on the internet don’t seem to bother.

I use coppaslip on the BB and normal grease on the seatpost. So far so good.
