What I can say Simon is that when I eventually unwound the asbestos wool from my Ulster tailpipe the exhaust was rotten underneath, but still sound where it was not wrapped. I'd always thought the heat would drive moisture off but apparently not. I had also painted it over with radiator paint to help prevent fibre shedding. Lasted 30-odd years though.
On the other hand, you could touch the wrapped section with the engine hot without real risk of harm. I only once placed an elbow on a bare Ulster exhaust pipe and will not be doing it again - never seen a blister so big and amazed I wasn't scarred for life.
Never tried it in the engine bay and I think the whole set of arguments is different.
