I've used Rotring technical pens for shading 1/300th armour. The trick
is
to buy ink designed for marking overhead projector sheets. This will
adhere
nicely to most *clean* surfaces, I've managed decent coverage on
semi-gloss
models (ie ones where the matt paint hasn't dried properly). So, look
for a
suitable ink and you should be OK.
