Removed my old, original front bumper from my '29 Tudor that had a lot of small corrosion dots on the surface since the replating over 30 years ago. I used an old Harley trick to make them shiny as new....just wad up a piece of aluminum foil and dip it in water....elbow grease...then wipe dry with a soft rag. I put on a good chrome polish afterwards to help prevent any more rust and corrosion. They look good as new after over 30 years of sitting and occasional chrome polishing with expensive products which really didn't work. I thing my wife paid a couple bucks for a box of Reynolds Wrap...have heard of using CocaCola instead of water but the water works great for me...and doesn't attract the ants in my shop! Try it....
