AKA vapor blaster? I'm really interested in getting one, mainly for restoring aluminum motorcycle parts. I'm trying to get some quotes from a manufacturer on one right now that fits my needs. I've heard they are about 3 to 4 times as expensive as a soda blaster cabinet but to me the results are worth it. They say it seals the pores of the metal making it's luster last longer and if you have a motorcycle, that saves you hours of polishing! Once I figure out how to use it, if I get it, I'll be willing to charge a fair price to blast some parts for you guys. I just want to see if anyone else has any experience with one.
Here is a video of what the finished product looks like.
