You can buy blasting media (crushed walnet shell) from a sand blasting supply company for about 20 -25$ for 50 pounds. Should last quite a while.
I got about ten pounds of walnut shell from a source via the oil patch but don't know how they used it. Was visiting a friend today, and he had washed his media. Surprised how much crud was in it. It was still drying when I got there, and looked almost new.
