The video was quite impressive.
As an FYI, you can purchase some dry ice blasting equipment, new, for around USD $3K on eBay. No, it's probably not the same as the $15K versions used daily, but then again, the 7.5HP, three phase, belt driven air compressor I had in my car wash years ago is not the same as the small pancake compressor I have for my pneumatic tools, and not the same as the trailer-drawn ones using a car engine to power a road jackhammer. But these may be entirely suitable for "shade tree mechanic use" for some of the restoration work we may do ourselves.
If I was undertaking a full restoration today, and planning on doing a lot of work myself, this tool might be useful to have...and then sell it when done. I've done that with a number of specialty tools as I'm sure some of you have as well.
