In case anyone is interested, here is a link to the airbrush kit I got for 
spraying CS:

There are many compressors and many airbrushes out there, even on this website, 
and there are many very expensive ones, but the kit above is still $149 for the 
airbrush, which comes with two different reservoirs, including a glass one 
which I prefer, and the compressor is good for 20-30 pounds per square inch 
steady flow, which gives some authority to the spray.  It has a regulator as 
well, and a small builtin tank.  Nice little system for the price.

The low pressure makes it safe to spray anywhere -- eyes, nose, mouth, and 
anywhere on your skin.  And while you're at it, do under your arms, and you'll 
be good to go all day without clogging your pores with aluminum.  :-)

I sound like an ad here, but I have no affiliation with the company above.  
Just like their product.  And I'm open to others if you find a better deal or 
equipment.

Cheers
