Mine showed signs of cracking as did my son's. Just went to West Marine got the fiberglass resin and hardener got the fiberglass at lowes, pulled the batteries and put down 2 layers of fiberglass running it 1/2 way up the sides. Problem solved that was 14 years ago. Then you can pull the covers off the A/C units and put down a layer or two of fiberglass on the inside to keep them from cracking.
