I didn't think about the clouding over thing, I kinda figured it'd happened to a lot of my storage bins because they were outside, but it makes sense. I had an idea of cutting a square out of the front top bin to cover with screen. It was initially for ventilation, but now it would also serve another purpose. I worry about the Silicone adhering, but it seems okay so far. I'm also considering how to access the inside. Normally a lid suffices, but with how tall it is I've been thinking either a hinged door or a panel attached by Velcro, but I'm still planning it all out. Thanks for the info John!
