Bead blast media type

[Mikej]

I have titanium frames and access to a large media blast cabinet. Does anyone know the specific media type / size that Built / Eriksen/ Moots use? Before I bug Brad-

We use a 175-230 mesh glass bead for our hammers and get a slightly brighter finish than most of the frame builders. Not better or worse, but we like it. Downside is we need to do everything twice, once with a course media and then with the extra fine stuff. Basically like a rough and finish sand paper.
