OK, this is the thread I was looking for. what a job, and what a good job!
We've had the same thing, where what seemed like a small, localized issue just grew and grew. Our trailer is empty now (well, we left in the ceiling) and we're not started yet on the fiberglassing of 31 holes (counted so far), but have checked the belly band and are wondering--
What is rot knot? When I looked it up, it's some kind of dreadlock shampoo. to prevent scalp and hair mold. Is that right? It's got to be non-toxic to people, and we don't mind, but would like to know we're getting the right stuff.
