3. Airbrush your favorite rubber color.
4. Remove the masks.
Now, using a well thinned black enamel and a fine brush, deposit some
paint in the hub recess. The paint is not as diluted as you would do
for a wash, just enough to make it flow by capillarity around the hub.
Since the paint is thin, you may need to retouch raised details later
for a complete coverage.
7. Once the hub is dry, paint the fork
with the appropriate color (RLM 65, in my case). If you want, apply a
oils wash and/or drybrushing to highlight the details.
