[Milsurplus] Refinish radio face with recessed lettering?

[Alan Barrow]

Hello all,

I seem to remember there is a trick to refinishing face plates and then 
refilling the recessed lettering with white paint, etc.

Memory fades, but I seem to remember these approaches:

- flow pen to carefully fill in only the recessed lettering

- touching up the lettering, then wiping off the excess, leaving only 
the recessed part

Is there a preferred way to do this? Or a web reference?

Thanks in advance,

Alan
