Would there be any difference or advantages to using a metal polish with a felt tip or using a pumice powder with a Dremel tool along with the appropriate fittings? I've already soaked everything with WD40, white vinegar, and dish soap to get the grime and a lot of the rust off the T rods, lugs, and washers. I've generally have always done this by hand but it's going to be too time consuming. Any suggestions on where to get these supplies? Thank you for any input.
