I have a cheapie Campbell gun and an old Craftsman hopper that I use on small jobs. The hopper has a screen and I've used play sand with good results. I assume that you'd still need to use safety precautions just like anything else, but I figured that it's cheap enough and more "get it all over your driveway" friendly.. With my compressor, there's enough pressure for small jobs, and like mentioned already, you don't want to use it for large flat surfaces.

I had rust around my rain gutters, so I cleaned out the caulking and blasted it clean. Works really good for the hard to reach areas.
