I have never seen the process done with that particular media. However, from common sense I would only assume that if there is enough action with any media that can remove paint from using the end of compressed air nozzle that someone not knowing what they are doing could warp a panel.......When you strike metal with any media from a projectile (nozzle), long enough it acts like a peening hammer and "moves" metal. I could put sheetmetal in my abrasive blaster and literally reshape it if I stayed at it long enough. Agreed, this media is very light and unlikely in the right hands but "right hands" is the key here.
On the other hand, blasting does generate heat. If you don't think so, aim a media nozzle at the end of your rubber glove. It gets hot in a couple of seconds.
So there is really two issues. The media, air pressure and length of time in one spot has a great deal to do with the results and the heat\warpage generated.
Now apparently the claimed benefits from soda are :
Unlike abrasive sand blasting, sodium bicarbonate particles remove contaminants by the energy released when the particles explodes as they come in contact with the surface to be cleaned. Sounds good.....Please post pictures of the results.
