I had a little spare time this afternoon so I figured I would attempt some home soda blasting. Using my little Michelin compressor (which works great for tires and painting) and a cheap blasting gun with hopper I had at it. I might have done better with sifted baking soda, but the bottom line was that there wasn't enough velocity. A larger compressor will likely be my next kijiji purchase. At least I can see the potential from what little came off from this side by side comparison.
