Polished all over (8)
I believe the answer is:
finished
This clue is a double definition.
'polished' is the first definition.
('finished' can be similar in meaning to 'polished')
'all over' is the second definition.
('finished' can be similar in meaning to 'all over')
(Other definitions for finished that I've seen before include "Brought to an end" , "Ended. completed" , "Done, over, ended" , "wrapped up" , "Complete" .)
