The salesman did give me an name/address of a company that sells equipment, media, and does the blasting as well. I will be taking a road trip down there, to check it out. He did say I shouldn't have any problem using it in my blasting cabinet...I'll keep y'all posted.

I did a quick look-see about soda, and ran across a site that also sells a media they call "super-K" which is potassium sulfate. Similar qualities to soda, water soluable, environmentally safe, doesn't produce heat, non abrasive, won't damage substrates but they say it's a harder crystal than soda so it works 30% quicker and will remove rust. They recommend it for auto restoration work. they say soda and super-K leaves a protective film that reduces flash rusting so it is not necessary to prime immediately like with sand or other abrasives.

I used a machine to strip paint from aircraft which used high pressure (10,000 - 12,000 psi) water injected with baking soda. Yes, this was definently commercial grade equipment and required perioidic maintenance. It stripped the paint and left a definate baking soda "taste" in the air. We were intructed to ensue all cracks and crevious were completly rinsed. The finish of the aluminum was slightly course, less than that of sandblasting. If you try the soda and it doesn't work out you should have enough left over to keep your fridge fresh for years!

I know they are becoming more and more popular with the resto-guys, because of the environmental and physical impacts, and the flash-rust prevention that was mentioned earlier. It is reported that it removes paint, without the heat build-up, then you can spot-sandblast the areas that need it.
I'm willing to give it a try - I haven't bought a pressure tank yet, for the "outside" work, but if this works well, and I have the horsies on my compressor (I'm running over 100 gallon tank), then I will lean that way.

I just ordered a 100# sample of some soda to try blasting my cab. Sales guy told me much the same info as listed above. He did say that the volume of soda material required through the blaster would be MUCH less than I was used to with sand. He said I would waste a lot trying to dial in the right setting. As I understand it, you want to use high pressure to create a 'hard' impact of the soda against the paint and a chemical reaction is as much a part of the removal process as is the coarseness/sharpness of the soda.
Roger, I am very interested in hearing how you make out.

Roger,
Wow, that's really encouraging....
You mentioned taking a trip to a supplier... where might they be? My source said the closest to me was Atlanta. Another supplier I emailed responded that the smallest amount they would ship was 400# and they generally figure $2.00/#. Norther Tool has some on their website and it works out to approximately $1.40/# (50# for about $40 plus $30 shipping) I'm still waiting for my sample.
