Tom,

I used Polyken Foilastic on all the interior metal of my van. MUCH
cheaper than FatMat although it is not a soundproofing material but
more of a sound deadener. Foilastic works really well and has quieted
the van down considerably. I have zero concerns about any water
getting underneath the Foilastic. It is super adhesive and super
pliable and I don't think anything is going to get under there. Once
you put it down you are not getting it back up again without a
serious fight. I used some 3M spray adhesive---the foaming version to
secure the carpet to the foil side of the Foilastic. The foil is well
suited for any adhesive and the carpet can be removed without
trashing either it or the Foilastic. The adhesive smelled a little
for a couple of days but no biggie
