Finish Line Anti-Seize Assembly Lubricant 8oz Can
Prevents cold-welding, galling, and seizing of metal to metal contact parts, especially those subject to extreme pressures and moist conditions such as bolt threads, seatposts, pedals, bottom brackets, etc.
Ideal for all metals, but essential when attaching reactive metals like titanium, aluminum, and specialty alloys and magnesium.
If you have any titanium on titanium action going on, then this is a must. As mentioned in the description, titanium is a particularly reactive metal. This means it has lots of loose atoms that like to bond with other atoms, even if they're in separate pieces of metal. Cold welding then occurs where the two separate parts become one. And now, your bottom bracket is permanently fixed inside your frame. If you are using almost any other combination of metals, grease or blue Loctite are usually sufficient.
