receiver snug to protect the internal surfaces, and throughly clean before assembly.
The sugar sand does a nice job that is non-reflective.
I hope this helps.

Is that like the "play sand" at Lowes? If so that certainly has the benefit of being cheap and easy to find locally.
Another question. I'm not going into business doing this so I don't need the biggest and best equipment, but I hate to buy junk too. There are several setups available at Harbor Freight and Northern Hydraulic but they all seem to need a pretty big compressor to operate.
I have a 5HP 17gallon tank compressor rated at 6.5CFM @ 40PSI and 5.1CFM at 90PSI 150PSI Max
Are there any decent media blast setups out there for gun work and other light utility type work for ~$150.00 or so?
The one I was considering is here: Portable Abrasive Blaster Kit
Air consumption seems to easily fit my compressor, and it is certainly cheap enough.
