nope because you could always grab some 3mm spray glue for 4 bucks.

Okay, so next question.Lets say I use this stuff here http://cgi.ebay.com/ebaymotors/100-Ft-FatMat-Car-Sound-Deadener-Free-Dynamat-Roller_W0QQcmdZViewItemQQhashZitem120282335184QQitemZ120282335184

Would it be difficult to glue carpet over that?

I wouldn't put asphalt mat on my roof even if the company paid me to do so and let me screw its cute little sister.

It says it's butyl based, not asphalt.

Black butyl based rubber solid with a 3 mil highly reflective polished aluminum constrain layer, wax paper release liner

And yet its asphalt. I guess you can really trust those guys who are selling that crap, huh?

Nice.

Ebay is a con-man's dream come true. You can lie all day and take people money and they can't do shit to you.

Good call, and yes, it is asphalt. After a lengthy argument with the new owner of FatMat, he agreed to remove the word butyl from the main FatMat Web site. Guess he "forgot" to remove it from his eBay auctions. Asking how FatMat was different than Peel & Seal (which he also sells through his primary roofing supply business) ended his participation in that thread //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Expanding foam in existing supports is a good idea (read the precautions carefully). I'd definitely look at adding some ribs, either thin wood or maybe aluminum, glued in place with some heavy duty construction adhesive. Fiberglassing over that might work well, but you haven't lived until you've tried fiberglassing over your head. Then I'd apply sound deadener in between the ribs. Then foam, carper, etc. to finish. In addition to everything else, it should make the vehicle much nicer to drive in the rain.
