So that part is dangerous to open, eh? You cou ld get bitten!
(couldn't resist ;))

Does the pot have any opening where you might get this spray in?
Some people report that some times of contact spray are too aggressive
and will, after improving a pot, make it fail quickly again.

I have used this particular product on the main volume pot of my trusty
Technics HIFI amplifier which was basically unusable for the left channel.
This must be now 7 years ago or so, since my treatment with the
generously injected spray, into every opening I could see on the pot.
Still working like new - so this particular spray seems not to be one of
the too aggressive ones.
