Commonly called "Copperslip" or Copper grease" however remove all the rust and
corrosion you can see and remember that the the angle between the hub and the
disc/drum surface is a sharp 90 degree althought it will seem to be a radius
that is pure crud so remove it with a file or something similar

High temp grease - such as Wurth 3000 - a thin coating - works just
fine... BTDT for about 20 years of BMWs now.
