b. Spray tone no further than 2/3 or 3/4
of the way up the page.
c. Stop spraying the tone shorter with
each passage since overspray will
build.
2. Figure 15 is a combination of
masking and varying shades. This
spraying exercise trains the eye to
make sure each square has the same
tone value. Repeat the spraying
method described in steps 1a-1c to
achieve the same tone value.

three times, fading to a different
corner each time. Ensure spray area
is adequately masked to contain
overspray.

after use. Do not leave spray material
in cup for long periods of time. Dried
spray material can cause damage to the
internal paint channels of the air brush.

2. Wash inside of cup using a bristle
brush dipped in the proper solvent
or clear water.
3. Fill cup with the proper solvent or
clear water and spray until clear.
Prevent o-ring
damage by
removing valve assembly and head
before soaking air brush in solvent.
