Media Blasting versus Sand Blasting

Even though I've had my Patrician for more than 18 months now, I'm still a babe in the woods with respect to mechanics and this whole restoration game. My latest quandary revolves around the effects/efficiency of media blasting versus sand blasting parts.

I currently have a nice soda blaster that I purchased last year from Harbour Freight and have run about 50 pounds of baking soda media through it. It did a nice job on the fuel pumps that I rebuilt and I plan on using it on the bendix treadle vac master that I'm currently re-building.

I have a good friend who is in the auto body/restoration business and he has been telling me that media blaster are fine for removing paint, but they do a lousy job on rust. for rust, my friend claims, you need a sand blaster otherwise the rust remains.

I haven't yet had to media or soda blast some severely rusted parts, but I am concerned whether the soda blaster would do the job. Anyone have any thoughts or experience as to which is the better of the two and, especially, whether what my professional friend has told me is in fact correct -- that only sandblasting will remove rust.
