I want to refinish a new Amphibian 090 to a fine satin finish (not brushed etc.) My thinking is that it would be quicker to get unifomity to start with a polished case and bring it down instead of going from the matte to satin. Any one done this enough to have an informed opinon? I've done a bit of metal work so I would probably just hit it with 400-1200 grade paper, followed by a light compond. Other suggestions are most welcomed.
