Spots are fine, not quite rash (8)
I believe the answer is:
freckles
'spots' is the definition.
(I know this)
'fine not quite rash' is the wordplay.
'fine' becomes 'f' (abbreviation e.g. condition of old coins, books).
'not quite' means to remove the last letter (most but not all of the word).
'rash' becomes 'reckless' (rash can mean impulsive or thoughtless).
'reckless' with its last letter taken off is 'reckles'.
'f'+'reckles'='FRECKLES'
'are' acts as a link.
(Other definitions for freckles that I've seen before include "Brownish spots on the skin" , "Small brown spots on the skin" , "Facial marks" .)
