Verbal report of one missing glossy coating? (7)
I believe the answer is:
lacquer
'glossy coating?' is the definition.
(type of coating)
'verbal report of one missing' is the wordplay.
'verbal report of' shows a homophone (sound like) (how it might sound if spoken).
'one missing' becomes 'lacker' (someone lacking something).
'lacker' sounds like 'LACQUER'.
(Other definitions for lacquer that I've seen before include "Type of varnish" , "Apply a sleek, glossy coat" , "Hard shiny covering on wood and metal" , "Shellac coating" , "Hair treatment; tree sap" .)
