well, so far all i have done is tear off the half loose pads, cleaned up all the old glue from pad and tube.
now i am ready to try again..
i dont have a good place to actually do this job.. (cannot be in the sun and must have low humidity).
btw, the instructions that came with the pads indicate that you should NOT deflate the tube.
i found some strong guide lines on the web

I FIND THE BOTTOM COMMENT A LITTLE IN MY FACE...:
Believe us, we do not enjoy grinding off dried glue from a botched job. You won't either!
but i can totally agree, grinding the dried glue off is annoying work and not at all as easy as one could think.
My conclusion is to take the inflatable apart/deflate, take it home to the garage and do the job away from the water.
