Review on Dynamat 11103 Dynaliner Self Adhesive Deadener by German Diaz

I installed this product on my firewall in addition to some Dynamat Extremes. This affects the heat and tone of my exhaust even more than the Dynamat Extreme which I was impressed with as the Dynamat Extreme alone makes a huge difference. I had to replace the heater core, so I installed it at the same time. for more thermal insulation. I accidentally spilled some radiator fluid on the Dynaliner when installing the heater core and it doesn't absorb fluid like they claim. It's thick and quite sticky. You'll definitely need a good pair of scissors or a fresh razor blade to cut it clean.
