Some numbers of accoustic loss (max is considered 1)
dynamat extreme second skin
0.081 @ +14F (-10C)
0.240 @ +32F (+0C) .16@ 32F
0.257 @ +50F (+10C) .19@ 50F
0.417 @ +68F (+20C) .29@ 68F
0.259 @ +86F (+30C) .20@ 86F
0.194 @ +104F (+40C) .14@ 104F
0.140 @ +122F (+50C)
0.094 @ +140F (+60C)
Dynamat Extreme $259 36sq ft
Second skin $139 50sq ft
The difference is large in the usable temp range, your choice

you're also comparing the lowest level SS to the top level dynamat
Since Ant is a member here, we get secondskin 40% off with free shipping, that means that 50sqft of damilifier is only $84 with free shipping. That's $1.68/sqft, compared to the dynamat xtreme which is $7.19/sqft. If you want to compare something closer, look at the STFU-80 compared to the dynamat xtreme. The STFU is better, and is still only $3.75/sqft. You could have 160mils of deadening by getting the STFU for the same price as 45mils with the Dynamat. It is mass afterall that deadens your panels, when you're comparing 2 deadeners that weigh the same, the only differences are adhesiveness, smell, and ease of application. I speak from experience when I say that STFU-80 has absolutely no smell, it's insanely easy to install, and it will rip off your paint if you try to take it off.
