In the past I've re-done these things by using a needle to dig-out all the old paint then spraying the panel with an acrylic-type rattle-can.

Let the paint dry really-hard [a few days] then go over the whole thing with 3200 Wet&Dry paper, which will remove the paint from everywhere except the engravings.

After that, a clearcoat with suitably-compatible lacquer.
