Another fun filled day.
Found some roof repair tape (commercial grade) Stuff was expensive 95 bucks for a 4" x50' roll. But buy once cry once on this part (and the spray on liner involved too much crying so I skipped that)
Also you can see some 3M undercarrage spray.

Getting on top

Prepping the surface

Tape down on one of the seams

And now with the 3M spray on top of that to seal any little bit o problem.

I used three cans of the spray but that was not enough. I think I am going to need at least three more, maybe four.
