Review on 🔇 S'mart Mat - RED 150 Mil 20 Sqft Car Sound Deadener Material - Audio Noise Insulation Reduction & Foamed Small-Meshed Polyethylene Heat-Insulation with Strong Adhesion by Tom Bennett

I used this material as the top layer of noise insulation in my twin engine jet ski engine cover. As recommended by the seller. I wore S'mart RED 150 onto a base butyl S'mart Favorite 90 muffler. Favorite was quite heavy and dense, and I was surprised that RED was quite light, like heavy foam. I also found it to be a bit trucker when applied - once the plastic backing was removed from the adhesive it stuck to whatever it touched, so great care was needed to place it correctly before pressing it down. Overall, the two S'mart products delivered significantly higher noise levels compared to the original egg-crate foam insulation installed by the shipbuilder.
