What I do is to spread a glob of white artists' acrylic on a palette
and the dip a stiff brush with the correct sand colored hobby acrylic
into this glob and apply it onto the model. Don't stir mix with the
glob and you will achieve tonal effects (sand/light sand) that will
delight you. The paint mix dries like artists' acrylic. If you
think you made a mess of your paint job, let it dry overnight first.
Adding artists' acrylics has a way of making mistakes appear as
skilled art.
There was an earlier discussion about scale effect of model colors and
that the way regular models are painted are way too dark. The white
artists' acrylic will bleach this effect and you can simulate sun
bleached sand paint very effectively.
One more thing you will need is a tube of clear gel acrylic
retarder/extender. It gives you more working time with regular hobby
acrylics as well as artists' acrylics. Also paint it over your
finished model (including the decals). Its effect is better than
dullcote or any other varnish..
I had been searching for a way to described the finished effect and I
think the Tamiya armor box art drawings are the best examples. The
Tamiya artist most likely used artists' acrylics and I think everyone
agrees that their illustrations are fantastic. Now just try achieving
the same effect with an air brush. You can't. Those brush strokes
need a brush to do.
