It takes a really big compressor, and it is a really, really loud process! I saw a demonstration a few months back where they showed the use of ice blasting for cleaning brick masonry facades. To be honest, it didn't have much success when used on calcium deposits, but it blasted layers of paint right off the steel pipes and conduits. Based on what I saw, I would wonder if it would be effective on pliable undercoating material...

Also, I was left with the impression that there are not many ice blasting setups in the country right now. The company that performed the demo was from Michgan -- and there was no one closer to DC.
