Hi guys got a second hand tank and cracked the bottom of the side pane when moving. Have striped all the silicone from inside the tank and will remove the end panel. The panel goes over the front, back and bottom. It doesn't sit inside these. Can I attach the new panel without dismantling the whole tank? I am doing a full reseal afterwards. I'm using Rhodorsil V2 silicone. Can I use methylated spirits to clean the glass prior to silicone?
