Engraving problems are best left with an engraver to solve.
I have a rifle that was engraved by R. J. Kornbrath that appeared to have had the bluing removed from the engraved area. Next to the others of the same vintage it just did not look right to my eye. Many times I had considered rust bluing the floorplate and trigger guard.
One day I called a friend and we talked about rust bluing and carding on engraving. He told me he had the same thing and was thinking of doing his as well. I asked who the maker was and he told me S.R. Griffin the same as mine. We stopped and regrouped and dug out the SRG files and found several that had been done the same way. Seems like SRG like the contrast so after bluing he remove most of it.
So even if you think you know what your doing let a pro look at it. Get a second opinion.
