Paint remover who reveals all! (8)
I believe the answer is:
stripper
I believe this clue is a double definition.
'paint remover' is the first definition.
(I've seen this before)
'who reveals all' is the second definition.
(a stripper takes their clothes off)
(Other definitions for stripper that I've seen before include "exotic entertainer" , "Progressively barer performer" , "Exotic dancer" , "Erotic dancer" , "One removing clothes" .)
