Generally happy
Style: Tech Pack 28 sqft, Style: Tech Pack 28 sqft
Much thinner than I expected, but installation went better than I'd thought it would. Needed to line the interior of the engine cover of a Ford E450 RV. Tried nitrile gloves, but they stuck to the material so did it bare handed. Cut easily with a fresh razor blade. Pressed in place with a plastic putty knife. We'll see the effectiveness on the next trip.

Makes For Quiet Rides
Model: 10 SqFt(0.95 SqM)
Comparable quality and performance to name brand competitor. It sticks on strong, easy to apply, and does make a difference in sound reduction. Turn your hollow shell sounding vehicle panels into solid sounding walls.
