Leave without good vinyl? (5)
I believe the answer is:
resin
'vinyl?' is the definition.
The definition and answer can be both substances as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for resin that I've seen before include "Tree gum" , "Sticky material" , "eg Rosin" , "Sticky tree exudation" , "varnish, perhaps" .)
