Hello Nels,
I've had reasonable results using a Sharpie Permanent Marker to fill
in toner transfer voids. They can be obtained at just about any
store including larger grocery stores. I've found them with a fine
tip at one end and a "ultra fine" tip at the other. Makes it nice to
have both tips on a single pen.
Sometimes when a quick board with a small amount of components for a
home project is need, I just draw it on the PCB with the
pen. Electrons don't care if the lines have size variation, etc.
