On a second look I found black deadener but nothing called black magic in their catalog, so it must have been discontinued. The Bomb is supposed to be the best (very thick), then Gold then Silver then the rest of the deadeners. Not sure where the black would fall in there as gold and silver have always had foil that is the color of their name.
I've used spectrum sludge before. It works pretty good and it's not as expensive as most deadeners. You have to let it dry for like a day or 2 though. Kinda time consuming and difficult to apply compared to just sticking on a sheet of deadener and calling a day. Good thing about it is getting into weird contours where you can't normally get to. Adds a good amount of weight.
yeah I want to stumble upon some bomb. I heard it was the bomb (no pun intended) lol
Yea it looks nice. If you wanna make about a $3-5k group buy I might know a guy who could get it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
yep it's butyl. It's amazing for the price
Yea it dries pretty hard actually. Takes a while though. I emailed second skin and they said they recommend about 2-3 days of drying depending on how thick you put it. Works really well though for the price. I've seen many people do spectrum on their entire car on the inside with a spray gun to get a good solid feel while driving. Sludge is much thicker and stronger though for our use. They're the same product but you add another product of theirs to make it all thick and slimy.
interesting, what benefit did you notice from doing the entire back of the panel like that? makes me think it might be a good idea. i wonder if it'd be tacky enough to use on the roof.Yea it dries pretty hard actually.

Here's pics of how it looks. this is from my old car where the 6x9 plastic panels were.
If you leave it alone, plastic will vibrate against metal surfaces and that particular rear deck panel is flimsy so it'll vibrate and make resonances and rattle EASILY. Adding it like that does a few things. Decoupling along with adding mass to reduce vibration and resonances.
well the headliner will go over it, im just concerned that the deadener wont stop the flex just slow it down lol good to hear it'll stick to the roof though, just will need to let it dry for a few days. seems easier than using wood and having to brace it for days
I'm interested to find out too. Roof flex is a b1tch. Hard to say if it'll stop it completely. Might have to end up using wood afterwards anyway as that's probably the most effective aside from a stripper pole. Whenever you get around to it, post up and let us know your results.
I have no experience with this, but I have read several times about using latex paint with microballoons in a 1:4 ratio. Item # B23/500-G, Micro Balloons On Wicks Aircraft Supply One person who suggested this to me is a veteran technician who I know personally. I can't recall if he compared this DIY solution to Sludge, but it was definitely a paint-on damper marketed for car audio use.
