Perfect surface texture (6)
I believe the answer is:
finish
I believe this is a triple definition!
'perfect' is the first definition.
(thesaurus)
'surface' is the second definition.
(I've seen this before)
'texture' is the third definition.
(thesaurus)
(Other definitions for finish that I've seen before include "Cease, conclude" , "Conclude, stop" , "End or terminus" , "curtains" , "Treatment of surface" .)
