Eternabond Tape on the edges of roof

been battling a cab over leak on my Coachmen 29' , like most Class C owners do at some point.

I suspect the water is getting down in between the roof and the walls, and runs down toward the cab, my driveway pitches downward at a pretty good angle. I've also had damp floor in the storage compartments along that same wall.

I want to put the Eternabond tape along the whole out edge of the roof, basically covering over that piece of trim that runs around the edges.

Has anyone done this? Does Eternabond have to be applied solely on a flat surface?

I had a leak in the front and it was from the coach front horizontal window around the edges. I fixed it using some asphalt rubber caulking product that held up real well.

While I was up on the roof, I did use Eternabond all the way down the roof edges on both sides after cleaning the surface real good first. It stuck solid and it is flexible enough to go over small things that are sticking up . I used it because tree branches were beating up the roof edges and sooner or later I was going to have a leak there. Its real durable stuff and has not come apart in 3 years now.
