I know we have all been though the sound deadener thing a few times, but I have another question. I have two different kits that I can pull from and was thinking it would be nice to use both as it would maximize my total coverage area. One kit is the basic repo kit like this: http://www.ss396.com/camaro/ICK-0137.html And the other is about 50 sq/ft of this: http://store.secondskinaudio.com/damplifier-pro-2mm-butyl-vibration-sheets-12-x-20/ I also have have about 40 sq/ft of this: http://store.secondskinaudio.com/lu...d-vinyl-closed-cell-foam-1-sheet-24x54-9sqft/ My question is what do you guys think the quality of the repo stuff is? Can I use the top two together without any loss in quality? The repo stuff is a bit lighter more like asphalt than the Second skin, but from the way I see it it is more about total coverage.
