So far this Spring the weather has been crazy with storms, wind and one day it is fairly warm and then back cold again. Over week ago, the temperature was 39 degrees/windy that next morning after heavy rain and cold front came through and i took a hand warmer to lay on top of my pot calls one was aluminum, just in a matter of few minutes the hand warmer was actually pulling moisture out of the aluminum pot call surface, this was surprisingly to see this happening. So don't think those cold damp morning aluminum pots will not contain moisture, because they will. None of my calls or hunting gear was left in the truck over night or whatever, all of my gear came out of a warm cabin for that morning hunt. Just something to think about with aluminum surface calls.. IMO....
