RC,
I boughta soda blaster from Northern Tool. The one I purchased can be for usedfor either sand blasting or soda blasting and I specifically wanted the soda blasting option. I live in town, want to do as much, of my own work as possible and was concerned about getting rid of the sand. My thinking was the used soda would be easier to dispose of. I plan to build a temporary blasting enclosure out of PVC and cover it with some medium heavy mil plastic. When complete with a blasting phase, my thinking was that clean-up/disposal would be easier with my waste blasting medium being contained inside my "blasting tent."
