Hi Tony
 You might contact Stephen Tonkin at webmaster_at_astunit.com. He is
in the UK and is also a telescope maker. I'm sure he can point
you to some place with supplies.
 I'm not sure what Doc is talking about with Cerium oxide.
It cleans up well and is a little off white in color ( sometimes
a little yellowish ). Rouge is really messy and will stain everything.
I've not worked wit chromium oxide so I can't say it is
better or worse that cerium oxide but I don't know how it
could be a powder and be any better.
