Your shop compressor will work, but is HUGE overkill.
Make sure you invest in an inline water-trap for the air pressure supply to the brush if using a shop compressor with a big tank.
A small $80-$100 airbrush compressor pretty much eliminates the need for this as there is no real air reservoir.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
