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

[Tom Frobase]

Here is how I do it.  Best product is Krylon lacquer  in a bottle, it 
can be purchased at your local art supply store, or white lacquer from 
the nearest hobby store.  Paint and fill the marker, let dry for about 
10 minutes.  Here is the trick! take an old T-shirt or something with a 
similar texture and spray a small amount of WD-40 on it.  Stretch it 
across your finger and lightly rub the surrounding paint until it is 
dissolved leaving the engraved section with paint.  It takes a little 
practice but believe me I have done many a 390 panel in that manner ...
