Anyone with a low power engraving laser can do it. It works with paint, preferably 200 microns. To achieve the effect, mask the panels once painted with old fashioned masking tape. Don’t use the silicone impregnated type. The lasers etches away the tape. Once etched, blow it off with compressed air to remove any residual “ash”, then spray the etched area with rattle can epoxy in a contrasting colour. Once dried, remove the masking tape and you’ll have nice sharp text.
