I just did all of my perimeter seams with Eterna Bond tape. I removed the loose caulking down the side seams as it had virtually failed although I had no leaks. I knocked off the high spots and excess goop on the front and back cap seams and taped over what was left. Not only does this stuff work but it improved the appearance of the roof 100%.
I'm getting more of it to redo all of the vents, air conditioner and skylight seams.
