Well I have this big Air Conditioner cage that I got from a closed Elementary school. I was going to make it into a boxish thing. I was wondering how well this stuff called "Coroplast" slides. Its in a lot of those election signs that like every politician gets people to stick in their yard. I got some with the right size and dimensions and it seems that I would slide well, but does anyone know from personal experience but I glue it on the cage?
