Two Europeans finish (6,6)
I believe the answer is:
french polish
'finish' is the definition.
(finish of furniture say)
'two europeans' is the wordplay.
'two europeans' means two replacements for 'european'.
'european' becomes 'French ' (France is in Europe).
'european' becomes 'polish' (Poland is in Europe).
'french'+'polish'='FRENCH-POLISH'
(Other definitions for french polish that I've seen before include "buff with this" , "Shine" , "Shiner" , "Glossy varnish for wood" , "buffer" .)
