Thanks for the reply John. It seems that cgoing had a great solution (previous post). I'll try the tubes with what is on there now and if it leaks, Ill remove and go to home depot for some new stick on foam sheeting.
But because you asked, I've attached a couple pics. You can see that the PO used silicon caulking to try to seal it. I guess the tubes were leaking and didn't create a good enough seal when only partially inflated. I'm trying to remove all that silicon and get it back to a smoother surface.
