Imoengnr was spot on about the micro pitting.
No amount of metal polish or solvents was ever going to clean them up as the pitting was two deep.
I thought about using a linishing belt on them but was concerned I might change the shape so I eventually took the safe option and attacked them by hand.
I started off with 80 grit wet & dry to remove the pitting followed by 120 grit then 600.
I'm an old fashion polisher and use the straight line method and not the circular approach as I always believe it's easier to remove straight line scratches then it is to remove swirls.
I also used this approach as I wanted the final finished to have the brushed look and not a mirror finish, so straight lines it had to be.
The first photo is after the 600 grit polish
The second photo is after going through a 1000 grit, 1500 and 2000.
The third photo is of them ready to be fitted after using some Mothers Aluminium Polish which I applied a first coat with a wheel then a second coat with a 1 inch rotary polisher.
I wouldn't call them perfect but close and I'm happy with the finish.
