[T2] Rust, Noise, Heat

[MUTS]

"Not a troll" disclaimer.
It is my understanding thqt polyisocyuranate foam (Great Stuff) does not 
seal out moisture, it traps it and rust will increase.  Same with Bondo- 
it absorbs moisture. Mice get into the hollow beam under the rear hatch 
and their corrosive urine will cause rust from the inside.  My engine 
rebuilder filled it with foam back in 2004 and it has still rusted 
through leaving foam in place.
