Easy Answer is that  double action Air brush can be adjusted to produce
a
smaller spray area then a single action. I have both. When work on
larger
items you can produce stripes and such with the double action. On mini's
both produce too large a spray area to do any detail work. However I use
an
airbrush to lay down  the base color on mini's. It produces a much more
even
coat. This really helps with colors that don't cover well. I can do a
dozen
light coats and not worry about too much paint or making the coat before
run.

I use poly-s airbrush thinner about 40% thinner and 60% paint by volume.
This works with most hobby acrylic paints. I have not used Humbrol
paints,
But I know it works with Ral Partha, Tamiya and Testers model master
acrylics. The deal is that you need a fine ground pigment, which most
hobby
paints have. A double action airbrush requires finer pigment and thinner
paint then a single action brush.
