2) Is it okay to use the Arm-R-Seal over a shellac sealer coat? I've got an issue where I tried to use an oil based ebony stain on actual ebony because it had some ugly light brown spots in it. The stain covered the spots, but when I put on the Arm-R-Seal they came back somewhat. I'm not exactly sure what's happening there, but I'm guessing the stain is not penetrating and the finish is redissolving it making a translucent black finish. You can't see the spots under normal lighting, but under direct light they are quite noticeable. I would just do a shellac finish but it's a jewelry box destined for a teenage girl and I don't think it would hold up.
