Yup, we've done things for boats and trucks and other places that have
nasty
spikes on 12V power lines.

As one example, take a look at the optional automotive power filtering
circuit of the QuickProto-01 (http://www.embedinc.com/products).  This
is an
OK circuit that will do fine in most applications.  For extra robustness
or
if higher currents were required I've used a series inductor instead of
a
resistor.
