I am making a DIY cage and I'm using plywood for the floors, laying flexwatt across the inside and attaching a thermostat, then laying plexi over the flexwatt and plywood on the inside. Because all my cuts are perfect, I have some cracks between the floor and the walls, what I can I use to seal the edge and fill the cracks between the floors and the wall. I was sort of thinking about aquarium glue, but I'm not sure if that will work. Any ideas or help, Thanks
