[R-390] OFF TOPIC: reworking a National planetary dial

[mlmccauley]

I have a National planetary dial, one of the ones that has the small 
windows spaced every ten marks in which a disk with the most significant 
digits of the dial position is displayed.

I got it off the e-place a while back, and while the knob, the mechanism 
inside the dial, and the external gearbox are all in very good shape, 
the paint on the outer dial, the one with the small vertical rectangular 
holes in it, is really trashed.

Here's my question. If I disassemble the dial, clean up the chips and 
scratches in the old paint, and repaint it, what's the trick to getting 
fresh white paint down into the "units" mark line recesses that are 
etched/pressed in/ground/? into the outer dial piece, and have it look good?

Thanks in advance!

73,
