Bo, check out the beginning and end of the video where he is knocking on the panel, I've yet to use lizard skin but will be doing so on my coupe.
Some sound insulation.

Bo, check out the beginning and end of the video where he is knocking on the panel, I've yet to use lizard skin but will be doing so on my coupe.
When I replaced my carpet I wasn't overly concerned with the sound deadening (I wanted to hear my triple Weber's at full song) but I did want to fill the recess in the floor pans left from the original material that I removed for both heat insulation from the exhaust and to level the surface for the new carpet. I used 2 layers of the rubber flooring material used in athletic training rooms.
I have no doubt that it works well. I guess I’ve been watching RetroPower for a while and I noticed they always Dynamat. Knowing how meticoulous these guys are I was curious if they had decided on that after making a comparison test.

I suspect there are more factors at play than just overall thickness (and even perhaps mass). Ultimately, this "stuff" needs to absorb the energy of the sounds (vibrations) within the panel. Interestingly, I believe with the Lizard Skin product that many people also apply their thermal insulation spray in concert with the sound spray. Each coating is that 40 mils (1mm). So together they start to resemble the dynomat system thickness.
I am a long way from having to decide this. But for me, I think the weight of the system would play a significant role. My car is not a CSL, but the lighter I can make it, the more agile it may perform/feel. This is a good topic to ponder.
