...the lug lining is a lot harder to do than it looks. I would suggest some experiment and practice on something else, first.
I'm still looking for some kind of paint pen that will produce a thin enough line to look good, and you might want to look for someone with a steadier hand.

A pin striping brush doesn't really work well, because of the difference in the surface levels. Here's one that is the best I could do at the time. Lately I've just skipped it.

If anyone else has a good tool for this, I'd be interested to hear about it.
