Soundproofing and Heat Control is often overlooked when building a classic muscle car. Yes, you don’t see it, but boy do you feel the difference. Not only does it keep the inside much cooler, it reduces unwanted noise and vibration. You can hear the difference in even the sound of the doors closing. We use Dynamat exclusively in all our restorations. Their wide range of high quality insulation products is made in the USA and is easy to install. It is well worth the extra investment in any build.
