I know of one off the top of my head that is not only very flexible, it has a bonding strength of 1000psi

Please lets not confuse Thiokol based Polysulfides with Polyurethanes!!! First polysulfides are not generally considered in the "adhesive sealant" category and secondly there is no commercially available polysulfide product that comes even close to 1000 PSI.
Life-Calk is rated at about 80PSI and 3M 101 has a tensile strength of 139 PSI and an elongation before break of 416%.
