Brilliant finish in church attracted to Catholicism? (6)
I believe the answer is:
chrome
'brilliant finish' is the definition.
(I've seen this before)
'church attracted to catholicism?' is the wordplay.
'church' becomes 'rome' (I've seen this before).
'attracted to' means one lot of letters go next to another.
'catholicism?' becomes 'ch' (I can't explain this - if you can you should give a lot more credence to this answer).
'rome' after 'ch' is 'CHROME'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for chrome that I've seen before include "A yellow colouring matter" , "'Silvery metal, resists tarnishing (6)'" , "Decorative plating" , "Hard stuff for plating - yellow pigment" , "shiny stuff" .)
