...then know it takes a long time and the quality of the "metal" was for me poor in places necessitating long periods of sanding.
The old Sodium hydroxide trick does not work - however it does turn the finish black but at the same time ruins it (very small bubbles) so my advice would be to lay off the caustic soda if you were considering it.
This still needs more polishing but I had to reassemble it to cheer myself up from the sit and polish, look at it, polish a bit more, look at it again routine
