It's one thing to seal up a car- its a whole other thing to not allow it to breathe, which I fear is what may have happened here if that bus really did rust out. Fibered roofing material doesn't seem like a bad idea as an undercoating, per se, but I would be careful where it was applied to. I think a more reasonable course of action would be to lay some (flexible, removable) panels of soundproofing on the floor and behind the rear seatback on the Fastback. It doesn't even need to go wall-to-wall, necessarily. In fact, I probably wouldn't go much larger than the original panel sizes, and with modern materials, it wouldn't need to be thicker. I would add a panel behind the rear seatback on the Fasty, as the masonite-covered-with-sisal seems to have completely lost its effectiveness by now. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
