I have an aluminum sign with engraved or embossed lettering... can't quite tell how it was done :-(
At any rate the coloring (black) is fading away to non-existence.
I vaguely recall that there is some way to "rub" coloring/paint/ink, whatever, over the surface to fill the lettering, then wipe the surface clean.
Anyone know how this is done? ...Jim Thompson
