For the heckuvit I tried some black silicon RTV by Permatex this morning. It didnt want to stick well to the pads either.

So I just finished applying the pads with 3M`s 08609 window weld. Its a urethane adhesive used when installing replacment auto window shields in place. I`ll have a better idea of its success tomorrow morning.
And in the meantime Im going to drill a few small holes and nut and bolt them down so I dont loose them as per TCledermans suggestion. If the adhesive works then I`ll remove them and fill the hole with more window weld.
