One of my favorite Bare Metal Foil tools is old business cards. I'll use a folded over corner to work foil into tight areas but one thing that surprised me was how well they polish the foil. I use the matte uncoated cards (or the inside of most matchbooks) and burnish just as hard a the part will allow. There almost seems to be a coating that this removes and takes it to near mirror finish without any scratching. The drawback would be that you can't really get into small recesses. I also use bus cards as scrapers to remove paint and glue or to absorb both from unwanted areas. So make friends with your HR People and you can score boxes of cards from former employees.
I use toilet paper, folded into a half inch thick block and dampened to press foil into shapes. This will press the foil into very small areas without tearing. Again squeezing as hard as the part will allow. I'll use a bench vice to squish foil into things like this 1/8 scale license plate style club plaques and such.
