Or, you could buy your own sandblaster, assuming you have a compressor to run it and a place to sandblast. I bought ($200 I think) a decent TiP pressurized sandblaster 5 years ago and I use it a LOT. I sandblast behind my shop where I don't have to worry where the sand goes. I wouldn't sandblast inside, sand gets EVERYWHERE. I couldn't find a TiP website but they are in Canfield, Ohio, 800-321-9260. I would stay away from the syphon feeders; I don't think they are very efficient.
