Problem with searching the forum is that not everyone uses the same terms to describe the same process! I did find these two related threads just now, for others interested:
"Lug Lining"
"Painting Lugs"
It seems that some recommend the oil based Sharpie Paint Pen. I might just give that a try on my Raleigh Sports to experiment. It is permanent, but does not contain led (like the enamel paints do).
I agree with you about the difficulty vs subtle choppiness trade-off with the brush vs pen. I have the same problem when rendering fine detail in artwork. Will try to experiment with both methods and see how it goes.
