What about the Dustless Blasting system that’s being advertised on the Velocity Channel programs? It seems much nicer than sandblasting, but I don’t know any particulars. The easier cleanup seems attractive.
It's
dustless not 'media-free'. So it's essentially normal media blasting carried by a liquid instead of just air. So the dust that's created is just washed away. But you're still media blasting -- just like using air -- and only preventing the dust.
Soda is highly water soluble: so you can wash the car out and get rid of the media. Yes you're hitting it with water, but I don't feel that's an issue over time.
Dry Ice 'melts' into a gas: so once you're done blasting, the media literally disappears.
Neither of these medias are particularly harsh, so any heavy coatings (like undercoating) won't be removed by soda/ice. The true way to 'geek out' on stripping your car, in my opinion, is to put the chassis on a rotisserie, and spend as much time as you can stand cleaning with scrapers and wire brushes. Think of the media blasting as the final step that comes in to clean up
only what you missed or couldn't reach effectively.
But that's a time commitment reserved for only the most thorough of restorations. I've only done it a couple times. Mostly it's just not necessary to go to that level for most restorations.
