[QUOTE="Rudy, post: 5543505, member: 568035"] I agree that testing should be part of R&D for any damping product. I'd also love to see a reliable way for us to compare results. I was lucky enough to see a huge quantity of comparable data from one of the premiere testing firms. Unfortunately, it turned out to have been leaked without authorization and I was asked not to share it with anyone. It did confirm what we already know - asphalt sucks and thicker foil is better than thinner foil. Not sure there is a lot of difference. Aside from damping performance, additives contribute to usability and stability. I agree with Ant that it would be hard to make a performance argument that favored one over the other. I don't know either. Tests performed to a uniform standard would be the only way to compare performance, but cost is the problem. A while ago I thought I had the perfect solution. Manufacturers could submit samples to a testing lab and pay to have their products tested. They would also authorize the lab to send me a copy of the results for publications. The lab was ready to go. I contacted several manufacturers and there was ZERO interest. Oh well. All we care about as consumers is that the product be durable and perform well. How that is achieved, in terms of materials used, isn't important. [/QUOTE]
