Second Skin Overkill Pro Closed Cell Sound Insulation Foam for Cars

OverKill Pro - 3/8 Closed Cell FoamFoam products are an excellent supplement to any vehicle sound insulation project. OverKill Pro is the thicker version of our flexible, rubber infused closed cell foam. Closed cell foams will do some work absorbing low-frequency sound waves and reducing distortions caused by sound waves in the door panel, but that's not what they are best at.
