Im at the sound deadening stage in my blazer project and I thought Id share a quick review of SS's damplifier pro, as Ive done alot of dampening before, but never with this product.Ive used mat deadening from dynamat original and super to the mcmaster-carr mat thats basically identical to dynamat original. Ive also used various spray on deadeners and even my own concrete concoction. But Im most use to working with the mcmaster/dynamat original stuff. Its good stuff, goes on easy once you learn to work it well with a heat gun, and it mass loads well and deadens decently.Well I decided to try some secondskin damp pro on my new blazer project, so I ordered 100 sq ft of it in addition to a small amount of the mcmaster stuff as a filler and where I need a bit more mass loading.To make a long story short, in installing this stuff (still a long ways from done tho lol), I had a metal panel that butted up a piece of the mcmaster/dynamat stuff to the damplifier pro. Same panel, the two pieces met basically in the center of it, just doing the tap-tap-tap method with my hands, fingernails and small tools, the damplifier side was noticeable quieter, and a lower frequency thump. Noticeably better. I was surprised, I didnt expect to be able to hear a difference in such a limited test. This ignores the fact that I already know it will be a better sound barrier as well. All this from a material that goes on easier with a roller and zero need for a heat gun, and is considerably thinner than the mcmaster/dynamat stuff. Impressive to say the least. Ive since removed the mcmaster stuff and covered the entire panel with damplifier.Ive been a big proponent of the mcmaster stuff since I found it (and found it was such a cheap alternative to the dynamat, which is -exactly- the same), but clearly this SS damplifier puts it to shame. Of course the damp is more money, but the results are noticeably improved. The mcmaster stuff is still a good low cost alternative, and an excellent all-purpose mass loader however.Im excited about getting the blazer on the road. Ive owned other blazers just like this one Id covered completely in mcmaster stuff, so I have a good reference. Is the secondskin damplifier pro worth the money? In my mind, no question it is, only a question of if you are willing to invest that much in this part of your project. BTW, iirc I payed something around $2.50 a sqft for the damplifier pro. Dont quote me on that price, if someone wants a more specific price I can dig up the receipt.Also, I have 2 gallons of the spectrum v2 sitting here I'll be applying to the roof and various places in the truck. As I said before, Ive used some sprays like Stinger and Rockford noisekillers, so I have experience. I'll post my results of how I feel the spectrum stands up to those other products once I use it.</blockquote>
