Put on fresh top and come out again (9)
I believe the answer is:
resurface
'come out again' is the definition.
('surface' can be a synonym for 'come out' so perhaps 'resurface' is OK for 'come out again')
'put on fresh top' is the wordplay.
I cannot quite understand how this works, but
'on' could be 're' (regarding) and 're' is located in the answer.
'top' could be 'surface' (I've seen this before) and 'surface' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for resurface that I've seen before include "Recover" , "Bob up" , "Emerge again" , "Come back up to the top of deep water" , "Once more appear" .)
