I does look like a dream when your done blasting. I have done sand blasting on a large scale. Logging trucks, low bed trailers and equipment. Huge compressor! Us shop guys took turns at blasting. It was a ruff job. Even with the proper gear. It did the job though. Great at making your refurbishment job a new fresh start.
I don't know how they would grind the dry Ice small enough and keep it from clumping and sticking together in the hose though.
