So, now we know how water molecules can migrate thru the

old plastic coated caps, (called bumblebees), or similar
old caps. Those are sealed real well, unless they develop
a crack.

They are NOT "sealed real well."
Nor are the old "Micamold" paper dielectric capacitors.

I just re-capped a Collins R-390A receiver. There are 28
paper dielectric capacitors in the one I worked on. About
20 of them were the Sprague bumble bee types, and the rest
were Sprague Vitamine-Q.

Go ahead and say it, "Collins! Top of the line! Mil-Spec!"
They were still crap capacitors
