Make a bag out of reflective insulation and tape it up with aluminum tape and toss your ceramic fiber in. Also underhood temps on my black ls400 only ever got to 160 degrees when i measured this summer. Don't go touching your headers or heat shield though.
I agree i hope my fiberglass insulation doesn't get wet. Its doing great for now as it doesn't get wet.
