This product was easy to use when spraying into hard to reach areas in the trunk and door panels of my Mustang. One can goes a long way! My results are pleasing.

Good addition to interior sound deadening. Installed an AWE exhaust on the OB Wilderness. It's a bit louder than I want to hear inside so trying to mitigate the noise. Bought two cans and it covers two coats in rte exhaust pockets including pulling the heat shield and two light coats on those. Doesn't over that much as everyone else noted. It did help reduce a bit more noise but not as much as the interior deadening of course. Planning to get another couple cans, pull the wheel well liners and do those too. Looks very nice. Just took another look after a few weeks of use and heavy rain - looks perfect.

This stuff is amazing. A little messy… But if you know what you’re in for it works wonders. My whole chassis was vibrating from a subwoofer upgrade to my rear quarter panel. Used this to coat the inside of the subwoofer cavity and it did exactly as it should. Nice and quiet. Will be using this again.
