Yes, scale tape works well. Put it on and trim with a razor blade. I will sometimes coat them with epoxy after the tape is on. I'm not sure what color it is but witchcraft makes a tape that looks like an oil slick, Its great on the flutter jigs. It makes a perfect non-committal baitfish that can resemble almost any shad or white-bait species.
I also just paint a lot of them pearl white with powder paint. Its a good color for the Great Lakes.
Or get nuts and air-brush them like Mo says. I end up air-brushing fire tiger ones.
