i used to be a roofer for many years and that stuff will not do you any favors for an extended period of time,if you wanna go the roofing route,they make this stuff called dibiten,it's a torchdown roofing that is melted on the backside with a propane torch and when it is applied to the surface it will stick and not come loose when it is hot out,but the downside is you must completely strip your car inside of everything and the gas tank should be taken out,your probably better off though using the sound deadener you would find here on this site or others.I hope this helps.

Has eneyone ever tryed Grace Shield as a dampener? It is a high end Ice and water shied for ROOFING, however just wondering how it would work since it is rubber based and a pill and stick. The product is thick and seams as it would do the trick? I don't know just thinking out side the box just wondering what people think.
