(c) Caring for brushes. For the lettering brushes to perform

Therefore, when you
clean the lettering brush, you must ensure the thinner is compatible with

oil prevents the remaining paint from hardening, which causes the brushes
to become useless. However, you must clean the brush and change the oil
after a month of non-use.

paints in brushes. (The GSA supply catalogue details this container.)
