You guys should probably know that Anthony is a sponsor of our Chevelle and is providing ALL of our sound deadening/controlling material. There actually is a really neat science to the mix of chems that create a specific sound deadening/controlling composition. For example, he's tailoring a batch of his Spectrum (spray on deadoner/controller) specifically for the Genesis Chevelle that takes into account the various components we'll be running as well as the grade of steel the car was built with. We got introduced to Anthony through our main sponsor RE Audio who uses his products exclusively. Great guy to work with and his products are really something else...definitely check them out on the site!
