Small truck carrying right tool for decorator (8)
I believe the answer is:
stripper
'tool for decorator' is the definition.
'small truck carrying right' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'truck' becomes 'tipper' (I've seen this before).
'carrying' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'tipper' placed around 'r' is 'tripper'.
's'+'tripper'='STRIPPER'
(Other definitions for stripper that I've seen before include "Her act is a revelation" , "She barely finishes" , "she reveals" , "Progressively barer performer" , "Waterproof boot" .)
