I am partial and biased on mass finishing systems because it produces better uniformity surface finishes. I'm not sure exactly what media to recommend because you did not provide enough info; however, instead of an abrasive, you might be able to use a burnishing media and brighten the parts instead of dulling them as you are doing now. To do the latter, you need a good chemical compound with the media.
