Since I was doing several square feet of aluminum sheeting on my firewall and engine bay fender walls, my buddy Mesa Mike used many 2" medium fine grinding discs with a high speed die grinder. He had done his car a few years ago so he knew the process. Didn't really take all that long and came out looking great. I wiped it all down with brake cleaner afterwards and then sprayed it with high temperature clear lacquer to cut down on oxidation. It has the look I want.
