I started a seprate thread (Are any parts of the X1C at risk of rusting in a humid environment?) to inquire about rust potential. Depending on how that gets answered, I’ll use either a thin 0.55 trash bag to seal off the X1C from the environment, or else I’ll upgrade to a 4mil trash bag (seems to be the thickest available) and use that instead. Moisture does migrate through plastic, but the thinner the plastic, the more/faster it will migrate.
