Found the leak.
Scraping the corners this afternoon near the bottom abdout 11' from the left when all of a sudden the scraper blade sank into the corner a bit more than usual.
After some more scraping I ended up with a 3' section (diameter). All of which had wet plywood underneath it. Hard to tell if the bondo failed or what but it's just about useless in this area and cracked in the seam. Will not be filling the seam with bondo again just PA and the tape. The area also feels a little loose so I will run some more screws into the area as well.
Also looks like the bondo in that area wasn't mixed correctly as it still had that fresh bondo odor to it and the PA didn't stick to it very well at all.
Letting it dry out over night then I will sand the area down, and put some more fiberglass tape in the corners and reseal the area.
