Check out this discussion:http://www.jalopyjournal.com/forum/showthread.php?t=711889&highlight=peel+stick I used the peel and stick on the floor and roof of my '54 it's been on over a year and zero problems even in 110 degree plus AZ heat.
fatmat is supposedly good, and cheaper than dynamat. Also there is an alliance member named lobucrod that sells a product that many HAMBers swear by. Here is his website http://www.lobucrod.com/ http://www.jalopyjournal.com/forum/showthread.php?t=366949 I originally used a product from home depot in mine made by frost king. A duct wrap of some sort many others had used. similar to peel n seal but not asphalt based. It is closed cell foam so water should be an issue. But after the yahoos had my car for paint it got wet inside and after getting the car back i ended up stripping all of it out. There were still pools of water in my floorboards that I had no idea were there, and this was over a month after I had my car home. Not good. So I have decided (and already purchased) Lizard Skin sound control and heat control and I should be spraying this in the next week or so. I probably will put fatmat over top of it, but lizard skin is similar in texture to bed liner and I wont be worried about my floor rusting out if water found its way in there again. My interior and dash are all out right now so I just went through the inside with rust treatment and then hit it with primer. Next is lizard skin sound control for the trunk, firewall and floor, and the heat control over top of that for firewall and floor.
