From my experience it dosen't stick very well compared to the Dynamat Extreme. It is an asphalt type sound deadener and is basically the same as peal and stick products available at the home depot. The Dynamat Extreme is much better quality, sticks better, with-stands much higher heat and is worth the money if purchased properly. I had to spray glue it to the door skin on my Cougar, but it sure made a noticeable difference when closing the door it sounded much more solid. For my Nova it will be Dynamat Extreme all the way. Buy the bulk packs from Summit and they will price match to any Ebay store. I saved $100 per bulk pack that way.
