I put the foil-covered buble wrap insulation in my doors.  It absorbs nothing
and was designed for sheet meytal building insulation...among other apps.  Water
is a problem in the front doors.  Even new window seals do not stop the moisture
from entering when i lower a wet front window.  Once when I opened the door
panels to find  it quite wet in there.  I don't see any rust inside my doors,
though...
