Never wrong about European facade (6)
I believe the answer is:
veneer
'facade' is the definition.
(I've seen this before)
'never wrong about european' is the wordplay.
'wrong' indicates anagramming the letters.
'about' is an insertion indicator.
'european' becomes 'E' (abbreviation e.g. EU).
'never' is an anagram of 'vener'.
'vener' placed around 'e' is 'VENEER'.
(Other definitions for veneer that I've seen before include "Decorative coating" , "Thin covering on top, as of wood" , "Evener (anag.)" , "Superficial appearance" , "Decorative surface layer" .)
