MAM11016- on the walnut shells, they come in fine and coarse. my first attempt was with Coarse.. (my thought was to use a clean shopvac, and then i could recycle the shells as they got smaller- starting with coarse)... but they clogged in the gun. I normally have tons of patience, but I just tried "fine" for a minute and it didn't perform quickly/easily and I switched to the Baking Soda. I didn't have the gun from the DYI, so that's probably why the Soda worked better than the walnuts.
