If you need to get 5200 loose, go to a marine store and look for a product called "Debond". It isn't fast, but it will make almost any of the urethane adhesives let go when given enough time and interest.

It’s interesting that you recommend Dicor. Maybe I purchased the wrong Dicor sealant (lap sealant) but the stuff I bought doesn’t ever dry - remains gooey. I used it to stop leaks at the top edge of the windshield weatherstrip and it remains gooey. In fact, the front cap paint is peeling and it sticks to the sealant. It did stop a lot of roof leaks but it sure doesn’t seem like a long term solution.If it were me I'd find some good thick aluminum, cut out a patch 1" bigger on every side, bend it, shape it to the curve and pop rivet it down, then Dicor over the top of it. Never silicone.
