Pete,
The picture was worth 1000 words. If you're going to keep this for your
own collection and re-sale is not an issue (at least at this point), I'd
say go to your local automotive paint emporium and have a small batch of
paint made up. RCarefully refinishing that small area is not at all like
trying to do the whole panel. Any reasonable collector (myself
included) would appreciate and necessary repair like you'd be doing.
Unlike pieces of vintage art, etc. vintage electronics aren't
value-destroyed by well-made repairs. That's why I'd say do just the
small area that's necesssary. Regarding remarking, if you can match the
size and font... have at it! Although nice to use, standard DATAK dry
transfers are all too obvious. Sometimes a complete refinish is
indicated, e.g.: a rusted out Halli. R-48. I had some decals made up
for several of those speakers and did a complete strip, pickle, and
repaint. Yeah, they're acceptable but I know the truth... so to speak,
but they're far better than they were. Regards and good fortune with
the project. de Jeep/K3HVG
