Loren, others:
Before you go to the mess of brush painting the bolster pins (remixing the
paint and cleaning the brush), you might want to look at the DuroColor paint
pens at Michael's Arts and Crafts. If the bolster pin is clean (wipe it with a
Q-tip and alcohol first if you are not sure) a paint pen is a lot faster
method.
Our "dots" are holding fast after 8 years, even on surfaces that get rubbed a
lot, like the bottoms of expansion track and hand tools. Its a solvent based
paint, not water based, and covers the black pins with a single stroke.
We even paint the sides of our rails with one, and that's survived track
cleaning for 8 years, too.
Just a thought.
