I'm just now finishing up the tan -> black interior swap in my 99 2-door LS. The Integra has more road noise than I'm comfortable with, however, and I'd like to keep that down as much as possible, ESPECIALLY in the rear. The interior metal has already been cleaned and is immaculate, and I sprayed down the spare tire well with rubberized undercoating for protection (since I seem to get water in there when it rains.) What does everyone think about spraying the backside of the rear side panels with this stuff? Think it'll help?

 

if you are that concerned with interior noise levels, then try some dynamat...though it will be adding quite a bit of weight.

 

dynomat or rubberrized undercoating

 

If you want a quiet cabin go for dynamat like material. My reccomendation would be eDead from Elemental Designs (edesignaudio.com). I have a RSX and was very concerned about the substantial additional weight that would be added to my car with heavy dynamat type materials, so i went with a liquid sound deadening solution (edead v3). Prep surface, paint, dry, repeat. The whole 1 gallon tank weighs no more than 15lbs for very great results/minimal weight addition.

i should work for these people.

 

What's that made out of? Rubber-esque stuff?

I definately do NOT want to go with Dynamat... it's too hard to make look good, it weighs a **** ton, and it's expensive.

 

hmm that eDead liquid sounds interesting. i have a lot of interior noise due to my sound system and i dont want to get dynamat because it is heavy and looks ugly. plus painting a rubber liquid on is much easier then using dynamat. does this stuff actually work and along with road noise, will it stop rattling from bass?
