I think keith Calhoan has an idea, I seem to remember a problem where the
pressure of nitrogen was released suddenly after a few days and it caused
bubbles of nitogen to form in the potting compound we were using, we had to
bake in a presurized oven to force the bubbles to go back into solution.
easy way to test, put some newly mixed compound in a clear container
pressurze and try releasing the pressure after a few days to simulate in use
problem.you might be able to accualy see the bubbles form when the pressure
is released.
