Ok, so I got this email from a China abrasive supply company which lists their products available. So I decided to post it here in case anyone was looking for an resource. This is not an advertisement. I just thought it would be good to share. I know nothing much other than this or how trusting their company is. Buying China abrasive would probably be a good inexpensive place to buy in bulk. I believe most abrasive is shipped from China anyway to the US.
You can read the post about ZOODAR ABRASIVE COMPANY and the abrasives that the supply.
If you know of any good reputable companies to list here, let me know by commenting below and I will do a write up about them. Also, please list resources for corundum abrasive.
