Casting under pressurre in high humidity

[PSNCO]

My thought process is that outside humidity should not affect PR or Alumilite under pressure.

Weather this weekend is partly cloudy, 75 degrees, 65-70% humidity.

I have not had issues here: sea level, 80% average humidity, 95+F average temperature (until today).

I'd be more concerned about water in my air line than humidity. Especially with Alumilite.
