Lou: You will like it, as it does a faster job than sand. Depending on the 
grade you get you may need to change nozzles. One note of caution - cut the 
air pressure back when you do sheet metal as it can 'ruff' it up. Nothing 
you can't sand out with a DA if you back the pressure off a bit. It, just 
like the other sand, hates water. Will plug right up. I have a water 
trap/pressure regulator rigged up on my blaster. This seems to work well. I 
have a pressure pot blaster. Run up to 60psi on cast and back it down to ~ 
40psi on sheet metal.
