Hi Andy,I used to do a bit of this back in the day.I had use of a buddy`s lathe and used that to polish/buff frames.Doing it by hand is a bit of a pain,deep scratches will need a fine wet and dry emery,also give tinfoil and water a go for light scratches,the rest of it should come up nicely with Autosol and patience.After polishing I used to apply a clear lacquer to the frame,make sure the room is ventilated,not cold and has no moisture.Its tedious but rewarding.
