As to exotic blasting you can also use dry ice, sponges, ground corn cobs,
pecan shells, walnut shells, oyster shells, coal slag, aluminum oxide, baking
soda, crushed glass, dolomite and plastic media. Then there are the steel
shot scarifiers... but I don't consider them exotic. Has anyone here got
experience working with any other blasting media?
