[R-390] ID plate repair

[David Goncalves]

I did the same thing :-) I'll be glad when the
cleaning/paining part of my radio restoration is done,
I've messed up more times that I'd like to say. The
following suggestions have alot of 'shoulds', which
means I have yet to do them myself.

You could touch it up with marker or a couple brushes
of model paint. It should look OK for little boo-boos.

The model paint should looks better - marker ink has
an odd shine; it looks like it is refracting light,
producing color waves on the surface.

For Major F-Ups:

As long as your ID place doesn't have gouges or dents,
this hint I recieved might help...

1. Strip off all of the paint chemically.
2. Spray on a gloss black paint
3. Wait till it gets dry and hard, days to months.
4. Tape down fine (600) grit sandpaper to a flat   
   surface.
5. Rub the ID plate on the sandpaper till all the 
   letters are clean of paint.

This should (since I have yet to do it) work, as the
tags are etched, leaving the letters and numbers
raised
above the background black. Sanding removes the paint
right off the top of them. Even pressure would seem to
be very important.

Fair Radio has repro tags for the R-390 for most of
tghe contracts, Hank Arney have quite a few more
(almost all R-390 and R-390A contracts, as well as for
some other radios) I just got one from him today, it
appears to be finished aluminum with silkscreened
black.
