16. If you’d like, you can use very fine finishing
sandpaper and, either by hand or with an electric
sander, selectively sand away parts of the image
(Figure 15.13).
HINT: A random orbital sander will give you
an even appearance, while hand sanding with
a rotary or band sander will create swirls or
grain in the work. Make sure you take appropriate safety precautions when sanding the
panel.
17. Since it takes acrylic polymer medium so long
to fully dry, I recommend waiting a few weeks
before sealing the surface. I like to use a paste
wax to finish these works (Figure 15.14).
18. Once it’s dry, place a sheet of white paper or a
mirror behind the image if you prefer a traditional frame. This will help highlight the image
and provide a deep, rich look. Or, if you’re going
to hang it with edge grip mounts, you can paint
the back (I use black, silver, or white, but you can
use any color).
