this fall i knocked off a bunch of the old factory undercoating and
resprayed with a heavy rubberized type available from the FLAPS.
also added a couple layers to other spots and coated a few areas that
weren't before.  was surprised in the noise changes.  now have a
whole bunch of new noises that i never heard before.

i have heavy rubber flooring in the mid bay and over the engine bay
as well.  these also deadened some noises.  i also lined the back
underneath the rear seat up against the engine bay with heavy rubber
as well.

an experiment that i did last month revealed some interesting data.
i had a noticeable difference in noises by filling the overhead cargo
area and putting a tight cover on it and sealing the front of the pop
top edge with duct tape.  also did some other tests at the same
time.  in the spring i will be redesigning that area.
