So, this is the current condition of my splashwell. See the area that has been sanded to bare aluminum on the grey primered bulkhead, it keeps warping and cracking.
I fixed all of the cracks, then noticed it had begun to warp. I braced it with some angle iron to get it back into shape, then warmed it with a torch to relieve the stress. A few minuted later, two cracks were back.
I have spent a lot of time on this splashwell, but I think I am giving up on it. It takes up a lot of valuable space, and without some major work will never support the weight of my kids monkeying on it.
Going to replace it with a smaller splashwell and a more usable platform.
