The roof issue.....
Across the front. Obviously failed.
Peeled off easily. Luckily there is a big layer of buytyl there, so its not leaking there.
But the sides don't have much butyl, and are leaking. Hard to see but you can see the cracks in the middle (i fixed the worst ones without taking pics)
So I took a knotted wire wheel to that area down the middle allllll the way around. That sucked. But it left me with a clean strip that hopefully the Sika will bond nicely too. I got the bare aluminum primer to use as well.
