Start using some paint rollers (5)
I believe the answer is:
intro
'start' is the definition.
(introduction)
'some paint rollers' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'INTRO' is hidden within 'paint rollers'.
'using' acts as a link.
(Other definitions for intro that I've seen before include "Song's first few bars" , "Start of work" , "Opener" , "Opening bars (abbr)" , "Opening instrumental passage of song" .)
