[QUOTE="jrock, post: 1908042, member: 78569"] Stainless rusts because (1) it is in a corrosive environment or (2) it has surface contamination. For a matte stainless finish, I used an AL oxide blasting media which gets it 100% flat. Then I spray glass beads with low pressure, just enough to knock down the rough surface and give it some more scratch resistance. This yields a flat glass bead look. Using glass beads on a smooth surface only makes it appear more shinny. Think faceted diamond but on a much smaller scale. In another life, I bead blasted nuts and bolts and they always come out shinny ready for zinc plating. Maybe a very large glass bead or maybe crushed glass would give a better matte finish. [/QUOTE]
