Sam's or Costco. Proceedure is simple. Just load into blaster and fire away. It can be used outside without need for an enclosure. No need to worry about getting any in the lungs since it is non-hazardous, enviromentally friendly, and washes away when it rains. It stings if you are sweating and you get it on your skin. No damage to you however. Protection still recommended. It is very fine and does not pit the metal in any way. I use it on chrome parts and it scrubs off the dirt but no effect on the finish. It really does a good job on the brake dust crap that likes to stick to the wheels. For more abrasion I then use Soduim that I get at the feed store. It comes in 40 lb. bags. These granules are larger and are closer to very fine sand. It will pit aluminum ever so slightly and makes it looks dull but nowhere near as bad as sand.

Obviously this is done with air and not the water blaster.
