I used to be able to dry brush dash details pretty good, but my eyes
and hands aren't what they used to be 20 years ago.
Some details I still dry brush, such as knobs...
I also have an assortment of trimmed toothpicks.
I even use the stick from Q-tips. I cut the cotton swab off the end and
dip the cut stick end in the paint (just enough to get a little on the
cut face). I then gently "stamp" the gauge details.
Maybe someone else will have a newer, better, and easier technique to share with us?
