Drives rig around that has a kind of patina (9)
I believe the answer is:
verdigris
'a kind of patina' is the definition.
(I know that verdigris is a type of patina)
'drives rig around' is the wordplay.
'around' indicates an anagram.
'drives'+'rig'='drivesrig'
'drivesrig' with letters rearranged gives 'VERDIGRIS'.
'that has' is the link.
(Other definitions for verdigris that I've seen before include "Greenish blue coating on copper" , "Green deposit" , "Patina on copper" , "Greenish-blue coat on copper" , "Green patina" .)
