I'm not too sure about bagging them up. I have bagged things up in supposedly in air tight plastic bags, only to come back some time later and find things rusted. I don't know of any trash can bags that are air tight. The thing is, they still breath, and if moisture gets in, (which it will) there is no place for it to escape as atmosphere conditions change. If you could find an absolutely airtight container, that would be a way to go. If you use an airtight container of some sort, release the pressure/vacuum first before an attempt is made to remove the lid. With positive pressure, your face print will soon be in the cover. Been there.... ![](http://www.film-tech.com/ubb/biggrin.gif) And yes, make sure the equipment comes up to room temperature and is completely moisture free-before it is powered up. If you do want to bag them up, do as Randy suggests. Get some silica gel desiccant and check it on a regular basis as needed. I would guess you would also be in good shape once it drops below the dewpoint and stays below that point.

I would also be wary of pest as well as moisture. Place whatever you are storing in somekind of sealed or partly sealed container and also maybe run a electric heater during the winter to help with the moisture. Keeping the enviroment as stable as possible will help condensation from forming. ------------------ Samual Hunter Sr. KC5ZSL

Frank suggested: >The air passing through the heat coils of the dryer will act >as a dehumidifier and will reduce moisture in the air that you >are blowing into the bag.No it won't. When you heat air the relative humidity drops because just as the term implies, RH is a measure of how much moisture is present vs. how much can it hold and since hot air can hold more than cold air the RH drops. But as soon as it cools back down the RH will return to the level it was before since you really haven't removed any moisture; it's all still there. Relative humidity, BTW, is what we feel and what causes condensation. The reason things seem drier in winter isn't because the RH outside is particularly low but because that same air heated up indoors is now capable of holding a lot more moisture and if you don't add any then the relative humidity will be low--simply because the air could hold more than it's got. So in that sense heating the air dries it out. But only as long as it stays heated!
