I'm rebuilding the front end of my car (raccoon collision), and I'm thinking if I line my wheel cowls with dynamat, that should cut down on road noise...

Is this a viable plan?

Thought I'd reply, wouldn't use Dynamat on exterior because of water penetration, possibly sound deadening spray.

I have thought about something similar, not sure it would work. I wonder if you could get the wheel wells sprayed with Rhino Liner or Linex truck bed liner? I guess they sell that stuff in cans as well at auto parts stores. From what I remember, Rhino was the softer material, might do a better job at sound deadening?

I know I've seen the black spray inside wheel wells before, surely there is a commercial product made specifically for this?

If so, maybe there is a version that can be applied by DIYers at home. Probably just need to have a prep procedure first, to ensure that the coating will adhere properly.

I used Noico sound deadening mats. It's a lot like Dynamat, but I placed it on the outside of the liner.

When you install the new liner, it is inside the fender well and engine bay, not exposed to the outside, or the wheel.

Oh nice, how was the process in removing the liners to get access to the back of the liners?

Not too difficult. I have one of those forks for pulling trim clips loose, and aside from one screw in the front (Which also holds the bumper on), and the 4 screws that also hold the mudguard on, there are only 5 of those holding the liner to the body and bumper. All in all, you can pull one in maybe 10 minutes if the wheel is already off. And you REALLY want to take the wheels off before doing this.

I second the use of the sound deadening spray, I have seen a thick black spray used that looks similar to truck bed liner, and have heard positive results from it, I don't remember the brand though. :unsure:
