Review on Optimize Your Sound Quality with STINGER RKU36 Roadkill Ultimate Bulk Kit- Enhanced Noise-Deadening Material by Ricky Habbani

Stinger Roadkill sound deadening material has been a staple of my cars for decades. It has always worked well and served for many years. The layer of foam on the Ultimate saves me from having to tape the foam to the gasket. Pros: Leaves are easily cut with scissors. The butyl layer adheres well and is excellent at removing resonances from metal and plastic. The foam layer provides thermal insulation, sound absorption and prevents the panels from touching metal (which can cause rattling). When everything is ready, the cabin will be noticeably quieter; My 4Runner is now as quiet as a luxury car.
