    Here are the pic updates(can this post be automerged?)
    The headliner was a PIECE OF CAKE!! FIRST TIME EVER IN MODDING! It's WAAAAAYYYY easier to remove the sunroof headliner than it is for the non sunroof and the use of velcro by Hyundai is genius

    So, how much more does your car weigh now that you've added all of this? Curious to know if you know how much you've added to the car. Not that it matters to you, as I know you don't race your car. I'm wondering also how much quieter your car will be on the inside...there should be virtually NO road noise now, except for the little bit through windows and the sunroof.

    Deadener really isnt all that heavy.

    Even the heaviest duty stuff is about .5lb /sqft. So even with the heaviest stuff, using 200sqft, which is WAY overkill, more than enough to do every surface at least 2 layers thick, you'd only add 100lbs and it would be evenly spread across the entire car.

    Stuff i used was about .4lb/sqft, and i used maybe 40-50sq ft and it was enough to do inner and outer door skins, 2layers thick, on all of the doors.

    +1 Tommy, and I will be racing my car on the auto-x courses. The stuff really doesn't add too much weight because like I've said many times I weigh less than 150lbs myself so adding an extra 100lbs to the car is nothing really but i'd say i've added maybe 50lbs I've used about 80sqft of the foil stuff and 25sqft of the liquid which is only 6lbs when cured.

    I still want to spray my fenders with the liquid stuff and spray the doors to cover the foil. I also am gonna get some more foam to put under the backseat and the trunk so that'll be another 10lbs

    That's right, I forgot how much of a light weight you are, my bad. And even if you did add 100 lbs, it's not going to affect you that much other than losing another tenth of a second, but that's in a straight line...hell, you've probably made the car much stiffer by doing this, so that'll help you out a bit.

    I bet your audio is going to sound sick!!!

    I'll try to get a video of it tommrow because it is insane how much of a difference in the sound level in the car is compared to outside, when I open the door it's like music vomits out of the car and I haven't put the interior pieces back in so hopefully that'll keep more sound inside.

    I just love banging on the door and it sounding like youre hitting wood. Slam the door and its like a Benz.


    Did you cover the door panels, and other plastics with foam? If you really want sound deading, you have to do that as well. Sound deadeners work 2 ways. 1 - the mat makes the panel phyisically harder to move, so less vibrations, less noise. 2 - you need something to absorb and slow the sound waves that do occur. that's what the foam is for.

    I'm thinking of spraying the liquid deadner on the interior panels after I scuff them with a scotchbrite pad so it sticks and then slapping the foam on, I'm still debating whether to do the floor because the foam underneath is kinda thick already and I might have an issue with putting the carpet back in. I may just cut some out of my old car and bulk the area around the shifter.

    So far I've reusued the old headliner pads from my gls, the poly stuff that was behind the dooor panles and that pad that was under the rear deck to add more OEM insulation to the car

    Dude, that line is worth rep...I hope I can give you some...I've never heard it put that way before. Definitely get some vids of you driving around, and then some of you playing music loud inside the car with the doors closed (you on the outside) and then open the door so I can hear the "vomiting".

    The liquid deadener is just another massloader like the mat. To get the full effect, you need a massloader and an absorber.

    go to the fabric store and buy some sheets of like 1/4" inch poly foam and some spray glue. the sheets will be sold as like seat cushions or something like that.

    3/8ths is pretty thick. Might be hard to get panels to fit right afterwords.

    oops, I meant the 3/8" stuff is what is going under my backseats and trunk, the 1/4" foam I am gonna glue to the plastic. I bought it off of a lab teacher on ebay 35sqft for like $14 crappy pic in post #70

    ah, gotcha.

    Yea, it makes a good difference. helps a lot with muffling any of the higher pitched rattles, lowers their frequency to something less noticeable, and then the low frequency road noise is almost stopped completely.

    Most of you seem to be deadening the sound to help with the systems you have in your cars. But what about someone who just wants to get rid of some of the road noise and vibrations? Would you still recommend adding dynamat/second skin/etc everywhere, or are there certain places that would give me that extra bit of quiet I'm looking for? I don't figure I'll need to do the trunk, but probably the front floorboards, maybe the front doors. The firewall? Thoughts?

    Floor boards, firewall, doors and roof.

    same concept as deadening for speakers.

    Anything thats Butyl based. Dont buy an asphault based deadner. They're not as effiecent, smell bad, and will melt into a puddle of nasty in your hot climate.

    I like edead45 - http://www.edesignaudio.com/index.php?cPath=1_24 - but its back ordered at the moment. They do have the heavier stuff in stock though, which is better, but more expensive and a bit tougher to work with.


    Second skin is about the best you can get - http://www.secondskinaudio.com/ - but itll cost you.

    Figure 100ft of mass loader (butyl dampener), probably 30-40 for absorption mat, and if you really want to go all out, get a bucket of paint on to do the floors with and the undersides of your fenders.

    IMO F everything else and just use second skin, you get what you pay for. I'm practically done w/ my car and w/ the windows rolled up it's borderline Mercedes style quite on the highway and street. w/o music playing and the windows up I can't hear other cars at all, even sirens are completely faint, i like it that way myself but I didn't kill the floor because I wanted to only have noise from the undercarriage so I could hear if there is a rattle or something.

    I also did the firewall and it cut out a good amount of engine noise but not enough so that you can't diagnose stuff. I was gonna do the hood liner but i'll wait to do that on the CF hood whenever it comes.

    I do still need to put some closed cell foam on the trunk floor under my false floor when I remake it and a little more under the back seats. I'll do the wheel wells soon with the rest of the liquid deadener I have.

    Hey I just finished deadening my trunk, and wiring 2 of my Big 3. On the wiring, I think it looks ugly too, but it works, and I may change it later. And now the trunk lid weighs about 25 pounds heavier, and will nolonger stay open by itself. Here are some pics:
