Good sound deadener?
x2 Second Skin makes good stuff, I've used them in a few cars with no complaints.

From what everyone has posted, it sounds like the top three (to pick from) are Roadkill, Raammat, and SecondSkin.
For the people who used SecondSkin, do you just use the "sound deadener" (the dynamat type stickon bytheral stuff) or do you also use the foam/MLV stuff as well?

I also use Second Skin close cell foam rubber(overkill 1/8", and overkill-Pro 3/8" thick) which I glue to their Damplifier with their spray adhesive. I used the Damplifier and Overkill-pro together inside my doors, behind sail panel speakers and on the rear qtr panels and trunk stump area in my Camaro. I didn't use any of the 1/8" thick Overkill.

edit: I just looked at the Overkill. It looks like it's basically a rubber infused closed cell foam (so a quasi foam/MLV hybrid?) so it has mass added to it (rather than just regular foam).
I was always told that the closed cell foam does little-to-nothing to stop sound on its own. It's only purpose is to de-couple mass loaded vinyl (MLV) from the sheet metal. Is this not true? Did you do a bore/after with the closed cell foam or was it all done at the same time?

From wut I understand, ccf only deadens higher frequencies where mlv blocks lower frequencies down to ~150Hz. If your goal is to block as much noise as possible, then using cld, ccf and mlv is the best you can do.
And yes, ccf is mostly good for decoupling surfaces from rattling against each other from wut I've found

Ive used dynamat. Its a quality product, that is grossly overpriced. Then i discovered others of equal quality at half the price, like roadkill. Sds has great info and price is decent if u want the whole system.
