[T2] Rust, Noise, Heat

[c.dreike]

Bob,
I placed 2 layers of Dynamat in my rear hatch and filled it with Great 
Stuff. The counterbalance springs now just barely hold up the hatch when 
fully open.  The Great Stuff sticks like a bugger to everything and 
would be difficult to remove. Keep in mind that it expands like mad. The 
rear hatch now closes with a satisfying Thud!
  I managed to buy a whole role of the NASA insulation from the 
manufacturer years ago and used that all over inside my bus on top of 
dynamat. The key here is to prevent any steel surface from getting wet 
and staying so over any long period as rust will develop. Any bare steel 
or painted steel surface is prone to having condensation develop on it 
at night or during cold weather. (Think warm bodies and steamy breath.) 
The Great Stuff should seal out moisture and prevent condensation. The 
linked paper mentions coating everything with Cool Patch which would do 
the same. I'm sure you read the paper so you know what the various 
layers of "gunk and stuff" are supposed to do. My bus is somewhat 
quieter than it was before I installed all the  "stuff", however still 
quite a noise box on the freeway. Maybe something to do with the wood 
paneled camper resonating and bouncing noise all over the place. Padded 
panels in the driver compartment made a noticeable difference in the 
noise level up front. BTW all my doors have Dynamat on the interior with 
NASA insulation filling the voids. As I have a garage queen I did not 
seal up the panels with plastic sheeting.

I live in Southern California so I'm not so worried about cold weather 
and a working heater.

Somewhere I have a print out of the original paper before it was dropped 
from it original place on the internet. Nice to see that the web site 
was resurrected via the Way Back Machine. Not sure, but I think the 
photos are no longer full sized. Interesting to read it again after all 
these years.
