helps prep a model part for paint. If you've done any sanding
on the model, or any putty work, you'll have high and low spots,
and an uneven texture.
the model part with primer allows you to sand the model with fine
sand paper to get a smooth finish layer to shoot paint on.
you can see an imperfection in the model part covered with primer
- you will notice it even more whan you cover it with paint.
primers can even act as a filler for minor imperfections.
primer is especially designed for models, which are often a very
smale scale when compared to painting a real car or a piece of
you use automotive paints, primer is usually required. Automotive
paints (or almost any paint not designed specifically for models)
can etch the plastic, sometimes even melt it. You need the primer
to help act as a barrier.
can also be useful for models that are molded in color. Shooting
a black molded model with white or gray primer can help with painting
the model a lighter color than what it was molded in.
Oxide primer is good for paint colors like red or orange, or yellow.
primer is good for dark colors, including black.
is almost good for any paint color, especially if you want to
lighten your paint color up some (for instance, when the model
is molded in a grey color as many are).
modelers have their favorite primer. Once they find one they like
they tend to stick with it for years.
puttys vary in the way they are made. White putty is most common,
though some are "red" (more of an orange color) and
some are green.
puttys, like the Squadron Green, has model glue mixed into it,
and it helps bond to plastic by sometimes melting it some.
modelers have their favorite puttys they tend to use for years,
so it's a matter of preference.
Acrylic primers are very fine, self-leveling coat that will help
give you a smooth surface on a model to apply paint. They also
wash up with water. They can be used right out of the bottle in
an airbrush, but can also be thinned for a super-fine thin layer
of primer on your model project.
you can use it in thin coats, one bottle can go for quite a while
and many models.
