Hi. New guy here. I recently ripped down an old 12x24 aluminum walled weismueller. hurricane sandy's salt water deluge turned the walls into swiss cheese. i've browsed the forums and am torn on how to proceed. i've got the wall up on my new 12x24 aluminum/resin coated pool but this one side pictured below concerns me. will hanging the liner [which seems to hang directly onto the top of the wall(?!)] and filling her up pop these wavys walls straight? my 4' level says everything is spot on. everything is lined up correctly, straps, pressure plates, rails. looking forward to hearing some good news and posting pictures of a perfect pool within a few days!
