Re: [ATM] re Various Polishing compounds

Where do you get Cerox?

Also, while we're on this subject, Microgrit rarely (never?) 
answers their email or online ordering. I am currently in 
the States and was able to call the only number I could 
find for them, which is an 800 number. When I called, 
the person who answered claimed they are now selling direct. 

CeO is quite expensive compared to SiC. I have mainly used 
#2 until now, but see Microgrit sells a #5 that they 
claim works well for this application, but is less 
expensive. Has anyone tried this, or maybe know it 
to be problematic, or will I be the first to compare 
it to the #2 CeO? 

I note that these are characterized for speed, but I 
suspect this is not a major consideration for most of 
us so much as getting a high quality polish.
