Here is the thread, there is some newer stuff out on the market they may work better, but I think it will be a combination of sound mat and the spray to really get to where you want to be. http://www.the370z.com/nissan-370z-g...html#post36972

Yes, I did. I don't remember the brand, I'll see if I can find it. To be honest, it didn't make a huge difference. It was subtle, I sprayed in directly on the inside of the wheel whels, it did lesson the noise of small rocks being thrown up on it, but not much for road noise.

Hey i was trying to find something to reduce the wheel well noise in my car and m4a1mustang told me to use sound deadening spray. He told me you used it so i was hoping you could let me know how that went. Im just triying to get rid of that particular noise and not dynamat the whole trunk. Thanks
