Hi,

Please correct me if I'm wrong but I think the older, vintage 'ceramic' cases for the Diastars, etc are made of tungsten carbide?

I've seen some two types of problem with those older cases, either cracking/chipping or discolouration and tarnishing.

I understand that there is not much to be done with the crack or chips, but is it possible to polish out the discolouration or tarnishing?

I saw another post on IWL where somebody referenced ScottJC and saying something about using Diamond paste to polish cases?

Thanks,
Slade.
