(Dynamat Extreme, brown bread, P&amp;S etc)On average they are 45 to 60 mils thick and all do the same job. Here is the catch, the thicker the material the less sticky it becomes. This is true with most all bituminous based materials.Also, some materials have higher temperature ratings.The higher the temperature rating, the less sticky, BUT!!!!  The lower the rating the more likely it is to fall of due to heat.It is a difficult task of combining the ingredients to come up with the perfect balance of adhesive strength and temperature tolerance.That is why dynamat has a patent on their material. They have a heat rating of 300f and still have a super adhesive product.Most other materials only go as high as 225.But, that’s also why Dynamat charges so much for their material.Now, if Dynamat were to make their Dynamat extreme 60 mils thick instead of 45 mils thick it would not be as sticky and would not work as well (with out lowering the heat tolerance)When I had Second Skin Damplifier made, I had to take all of this into consideration.  What an arduous task.Anyways, check out these products that are proven to have good temperature ratings and strong adhesive strength:Rammat, B-quiet extreme, Brown bread, Fatmat, Dynamat extreme, and Second Skin Damplifier.Hope this helpsANT</blockquote>
