Be prepared to spend a lot of time blasting models to get the paint off, and to clean up the spent blasting material. I doubt if it will do what you think it will.
I have one of the Badger units, only used it a few times to try and remove factory lettering from models. More or less worked, but left the area a different sheen than the rest of the model, so I don't know if it was worth the effort as it probably will still have to be painted.I made a special booth to use the blaster out of a translucent plastic crate, to capture the dust. I used the very fine sand that came with the unit. baking powder may be better but it too will want to go everywhere unless you contain it. I did my work in the garage so I wouldn't get the dust everywhere. I even hooked up a shop vac to the box to clear the airborne blasting dust. On another thread somewhere it was mentioned using the powder you need a real lot of it to do anything, the small boxes of it you get it grocery stores won't last very long.
I think special paint removing chemicals for models is probably the best way to go. I used some Polly S ELO (Easy Lift Off) and it worked fast and good.
Let us know how you make out. Good luck!

I finally got fedup (a division of FedEx and UPS Joke) with Brake fluid and 91% Rubbing Alchol spills and smells. I went on ebay and found a mini sandblaster by Badger I bought one. If anyone is interested here is the link

I was told by a professional painter this is a great tool to have now
Also found out you dont use the beads/ Sand that comes with it you use Baking Soda for the abrasive.
This isnt my auction and I wasnt asked to post it I just thought it might be something someone is looking for.
