I believe the answer is:

panel beater

I'm a little stuck... Click here to teach me more about this clue!

'repairman' is the definition.

'directors give whisk' is the wordplay.
'directors give' becomes 'panel' (I can't explain this - if you can you should believe this answer much more).
'whisk' becomes 'beater' (I've seen this in another clue).
'panel'+'beater'='PANEL-BEATER'

'to' is the link.

Can you help me to learn more?

(Other definitions for panel beater that I've seen before include "unanswered quiz question?" , "See car repairer" , "Body builder perhaps" , "triumphant on What's My Line?" , "Garage worker" .)

I've seen this clue in The Mirror.
