BEWARE of any insulation you place in your truck that
A) CAN absorb moisture - it WILL, causing the metal to rust like crazy. Get
nothing made of open-cell foam, even in a sandwiched material.
B) can HOLD moisture against the metal... this foil stuff should NOT absorb
- IF you buy the good stuff - but when placed against the steel and just
tacked in place in a few spots, it makes an ideal place for water vapor to
collect and pool. A good solution is to get spray adhesive and COVER the
dang thing, get complete surface-to-surface adhesion.
Closed cell foams are the best, and most expensive; they are often sold as
sound-deadener. Again, make sure there are no air spaces between insulator
and steel.
A guy I know has used that expanding urethane foam quite successfully;
closed cells, perfect adhesion. He sprays it, and then uses Saranwrap on
his hands to kinda mold the stuff into a thinish, even layer. Time conuming
and messy, but his 65 bus is warmer than anyone elses!
