Can only recommend one, which I use. Kno Knoise Kolossus Edition 2 Door Kit 14sq ft - Merchandise

This is enough for trunk lid and plate. Keep in mind this is 100mil stuff, not standard 80mil or 60mil.

Check the Socal thread. There's a guy selling roadkill for 90.00. Was going to buy it, but I don't have the $ right now. @xxxbasshead

Not dissing, but $60 for 100mil to cover the whole trunk is pretty hard to beat //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

and that shit is beefy man

I had the 80mil, applied it to my rear deck, and it's total hush now. The 100mil will work wonderfully

No worries brotha. Yeah that's a good deal. The roadkill would actually do the trunk and prolly 2 doors.

you dont use deadener for license plate man. You use weatherstrip foam tape from home depot to decouple the license plate from the metal, works 1000x better then deadener.

So wait does stuff like Damp pro (the foil with the glue on it) keep road noise out or does it just reinforce the panels making them not flex as much therefore not making as much noise? My understanding is to make my truck quiet is I gotta put damp pro all over everything metal and then line my floor with the Luxury Liner stuff... right?

Typically applied to the floorboard to kill road noise. Applied to the doors to seal the "box" and to stop rattling. Applied to the rear/trunk/roof to silence vibration from the subs. Does not have to cover every square inch though.

Damp Pro is a deadener. Its designed for 2 purposes. First is a viscoelastic layer (butyl) that absorbs vibrations and turns them to heat and dissipates via the aluminum layer. The second is by adding mass to a panel to change the resonant frequency.

You would use MLV or mass loaded vinyl to keep the road noise out and the audio in.

To do things properly you also need CCF or closed cell foam. Closed cell foam is used to decouple vibrating panels or 2 other surfaces that rub/make noise against each other.

Majority of post is incorrect. See above. The right part is you dont have to cover every square inch. The 25% rule applies. 25% coverage is where the cost to benefit ratio of covering every square inch just isnt worth it for the minimal gain you get.

I meant what most dampening is used for, not just the Damp pro mentioned above. Thanks for the better insight.

texted the roadkill guy, waiting for a response. Any other recommendations?

Been doing some research and have come to the conclusion that 36 sq ft of roadkill expert for 100 off ebay is a great deal
