When you say burnished back does the scotchbrite pad actually make it smoother (finer scratches) or is it coarser then the 600 grit. Just wondering.
Jeff:
Fact of the matter is I don't really know. My guess is that the Scotchbrite is about as fine as 600 but it works differently. Now that you mention it, it would be interesting to evaluate the finishes under a microscope. While the 600 finish is shiny, the SB finish appears just as smooth but has a softer look to it. I am inclined to think it wipes the tops of the ridges down a bit, which is why I refered to it as burnishing. In any event it makes for a smooth, well blended surface that seems to respond well to the bluing solution.
