Try pulling the Teflon lining out of a section of lined cable housing, long enough to span all protrusions in the BB area, plus several inches. Thread this on the cable, letting it overlap the points of contact. It should stay in place without cement (though you could always use something like JB Weld to hold it in place), and it will cut down both on wear, and friction. If you have enough clearance, you could put a complete piece of lined housing in the contact area.
