Luckily I don't have to deal with the rust proofing out here in Cali. I've already dynamatted all 4 doors plus the tailgate. When work mellows out and I've got some more free time I'm going to rip the seats and carpet out and accumat the floor, then I'll finally be done!Qxxx4 wrote:HOOOOOOLLLLLYYYYY SH*T BRO
and here i am bragging about rustproofing.
It absorbs some of the engine vibration and slightly lowers the amount of noise that comes through the cabin. I have 2 layers of it inside all 4 of my doors(inside the doors and between doors and door panels) and same with the tailgate. I've even gone as far as to "cushion" my rear license plate. It's made a massive difference on both the amount of road noise I hear and the way my A/V system sounds. If you took my same stereo setup and put it in an identical car without the sound dampening material the difference would be mind blowing. Plus if I turn it up you don't hear a single rattle inside or out. PLUS I can turn it up with the windows up or down and the sound stays in the car. The only tradeoff that I can see is weight. The amount of material I have added is probably about 125lbs worth, so your gas mileage probably suffers a small amount but my deal is probably slightly overkill.fukinitupagain wrote:Sound dampening? Eh, I wouldn't do it cause it would get soacked with mud & water. Does it really work though? Could that go in the doors?
It's totally worth it, I can't even describe how much more stoked I am every time I get in my car and I design really massive A/V systems for a living. So far I've used 72sqft of dynamat extreme and almost 36sqft of scosche accumat (for the ceiling) inside the vehicle.Qxxx4 wrote:so how much has all that dynamat cost you? and labour? id say its all worth it.
I remove the door panel, roll the window up and stick it to the outermost part of the door interior. Then put a layer on the area the door panel mounts to including around the speaker. I got a ton of cuts from that because the material has a foil like layer on the outside that is really sharp. Just imagine lots and lots of paper cuts all over your hands but deeper. It's a pain in the *** too because you have to cut it right so you don't block access to whatever you need like holes for clips and screws.bmlawless wrote:How do you do the doors? Do you just remove the panel and door the door assembly or do you actually get it through the holes and attach it to the door skin? That's gotta be a heckuva job on some vehicles.
