Yes, that's a siphon blaster. You can probably find one locally for less money and save time and money on shipping. Look at your local auto parts stores, hardware store, Harbor Freight, Northern Tool, or Sears, and maybe Walmart. All you need is the gun and the hose. Stick the hose in a bag of sand and connect the gun to your air supply and you can blast. Lowes has some good Premium play sand that works well for a reasonable price. Wear a good dust mask, since inhaling sand dust isn't good for your lungs. And a face shield. It's not as powerful as a pressure blaster, but it can get small jobs done.
