Soda blasting seems to be the least damaging of all media blasting. A look on YouTube gives plenty of examples. Said that Soda dosen't scratch glass, dosen't eat rubber, dosen't warp panels and for the most part, clean. When blasting outdoors and after cleaning up, the excess soda melts away with the rains. Price of media is about the same or less, with seemingly better results than plastic or walnut media, all other media is too aggressive and can easily damage and warp panels. If you have a convenient outdoor area for blasting, you could rent a unit or hire a guy with a truck mounted unit and split the duties, if you like getting your hands dirty.
