Thanx for the history. It helped a lot. Now we know at least there's some integrity to the setup.
Going the route you're going I would "ecapsulate" the rubber strip - meaning to sweep in a large path of silicone at the joint, lay in the strip and then sweep in another path over it completely covering it. Make sure the first sweep and second sweep meet so they can cure together.
Where I work whenever we have to use silicone on rubber we sand it lightly to give it more "bite". Irregardless. silicone doesnt stick to rubber that well. You could do the same with epoxy. I'm sure more ideas will fly through here by days end.
Let us konw what happens.
