The problem with the paint pens is that they don't keep so well. If
you are a hoarder like me you'll sooner rather than later be left with
a box of useless hard pens. That seems to happen much faster with the
"laquer" variety where you must pump the tip and hear a steel ball
inside when shaken, the permanent marker variety seems to store much
better.
One pen that works well on most etchants is the staedtler lumocolor
permanent marker. The red color is best (the ink is also used in the
marker for chemical lab glassware).

It only resists strong etchants without fail if the pen is fairly
fresh, so it is best to get the refill station so you always have a
"new" pen at low cost.
