### ⭐⭐⭐⭐⭐ Review
*by J***N on 25 January 2026*

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.
