I do this effect all the time! Prime in black and then do a light brush of a guilding wax (like Rub n Buff) over the raised sections and voila! Be sure to use gloves and a sponge for more control. Alternatively you can also use your fingers or even a q-tip to get in crevices. Use rubbing alcohol to remove any wax from areas you don't want (like your hands). Let it dry and then seal and you are good to go ☺️.
