Glass bead media is available in various grits. The courser the grit, the more dimpled the surface. Fine grit beads do not cause a problem with gasket and seal leakage. I always blast with a high pressure pressure cleaner several time after using beads.
Soda is very fine and single use only, after one or two uses it breaksvdownnto such fine particles it doesn't work that well, and being so fine creates a dust cloud inside the cabinet so you can't see what you are blasting. Being fine it also gets into very tight spaces and is difficult to find and remove. It also turns to mud when wetted.
Never used walnut shells, just not available here. It's supposed to give a good finish but being a softish material I'd imagine it would be similar to soda, single use only.
