They polish up pretty well lads! (sorry not the best of pics).
Simply insert a rotary wire wheel into your drill and carefully remove all the surface crud.
Then using an old rubber hook n loop backing plate, an old 4 inch coarse polishing pad + a coarse polish, buff to a high finish.
It would have been easier via a garage pit and simpler to remove the back boxes but the exhaust clamp looked too rusted to remove, so this will be another day when time permits.
