An end product of unusual lustre (6)

I believe the answer is:

result

'an end product' is the definition.
(thesaurus)

'unusual lustre' is the wordplay.
'unusual' indicates an anagram.
'lustre' anagrammed gives 'RESULT'.

'of' acts as a link.

(Other definitions for result that I've seen before include "Final outcome" , "Consequence in Ulster (6)" , "'Outcome, upshot (6)'" , "Verdict" , "Ulster (anag) - outcome" .)

I've seen this clue in the Evening Standard.
