The tip is another story but there is nothing that can be done about that.

I am open minded; it sounds like the grease will work. It may even be that the BERU Glow Plug Grease is the same thing with a different name on it. Give the grease a try and report back on it.
Howerer, the Glow Plugs are supposed seal on the tapered area just behind the heating element and no carbon is supposed to get past there to mix with either Never-Seeze or Grease.
I only put Never-Seeze on the threaded area of the Glow Plug. The fact that it has solids is part of how it works; it fills up the clearances between the threads (not allowing air and moisture to come in contact with the parts) in the Cylinder Head and the threads on the Glow Plug and when it gets hot dose not run out. It has certainly with stood the test of time.
