Committee wiping the floor after bodywork (5,7)
I believe the answer is:
panel beating
'committee wiping the floor after bodywork' is the definition.
I can't tell whether this definition defines the answer.
'committee wiping the floor after' is the wordplay.
'committee' becomes 'panel' (panel is a kind of committee).
'wiping the floor' becomes 'beating' (I can't justify this - if you can you should give a lot more credence to this answer).
'after' says to put letters next to each other.
'panel'+'beating'='PANEL BEATING'
Can you help me to learn more?
(Other definitions for panel beating that I've seen before include "Restoring dented car bodywork" , "Metal work's needed" .)
