I use rice, but if I were to go to anything else I would probably try the above.To date the 50-50 formula works better than any other ratio that we have found. We find that Corn Media Size 10/14 mixed with Walnut Media Size 12/20 does the best job.
Check under "Metal finishing suppliers" or "Blasting media" in your local Yellow Pages. I buy 50 lb. bags of untreated corn cob at a local supply company for $21.50 :dancingbananna:Who has the best best deal on untreated cord cob polishing media?
Dillon has it for 10 # bag @ $10.95 per bag. Better half told me to go buy more ( Dam I have a great wife):notworthy:
