When nearly finished lace, query protective coating (7)

I believe the answer is:

lacquer

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

'protective coating' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for lacquer that I've seen before include "Apply a sleek, glossy coat" , "Shiny varnish" , "Put finishing touches to" , "Shellac coating" , "Hairstyle fixer" .)

I've seen this clue in The Irish Times.
