I rehabbed an early (S/N/ 1200) Motorola R-390-A by using the following
procedure:

I did not try to remove either the existing paint or the existing lettering.
I just sanded the rough paint edges with #400 wet or dry paper and feathered
the edges.

I masked the front panel lettering with Scotch Magic Tape (either the stock
variety or the blue roller "temporary" low-tack kind) and trimmed with an
Xacto knife using a #11 blade as close to the lettering as possible.

I sprayed panel with two light coats of Ace Hardware Machinery Gray #17021
“Premium, Enamel.” Letting the first coat dry overnight and the second coat
dry for 48 hours.

I peeled the mask off the lettering.

I then sprayed the panel with two medium-heavy coats of Ace Clear Satin
#17014 Polyurethane Clear Finish, sanding between coats with #400 paper.
Then spray with a final light coat of Satin polyurethane.

(After spraying with gray enamed, there will be a depressed area in the
paint where the lettering was masked. The urethane fills this nicely and
makes the whole finish flat.)
