I mainly see examples of the white dots on sights being painted. Can this stuff be used effectively on the front fixed sight of my bulldog revolver??? I carry it at night with rat shot for snakes and a couple hollow points in it for anything else. It's the Charter arms .44 Spcl so the rear sight is only a slight recess, not sure how I'm gonna highlight that area yet. Also I've heard of using clear nail polish after wards to keep it from flaking. Anyone with any experience using the stuff I would be greatly appreciative to hear your ideas.
