    How did you guys do it, I'm torn between going end to end or just sticking long patches here and there between the headliner rod mounts...

    Thanks

    Depends on the material used. If using a vibration absorber like dynomat or some other sticky-backed material (I used Noico on my truck) then you only need like 20% coverage or something to effectively negate sheet-metal vibrations and resonance. If using an actual sound deadener like mass loaded vinyl (MLV) then you actually need 100% totally sealed coverage. Any holes and sound will pour through like water.

    So... what's the goal here? Resonance/vibration absorption? Heat reflection? Or total sound protection? This will decide exactly what material you need, and how much of it.

    Im using Thermo Tec suppressor heat and sound control, Im looking for vibration dampening not so much heat barrier but I also dont want to cover the headliner bow mounts and not sure if I should go crazy or just throw patches here and there.

    Anyone have pics of how you did yours?....
