Front wheel wells and some interior in the rear, makes all the difference in the world. It's like driving a cadillac.

Kind of pricey but well worth it.

The inside of the wheel liners were also coated with 1 can of undercoating material as well.

Pictures sideways, dont know how to fix and i think they are too big, sorry...

Glad I have a big monitor! I've thought about this...and one of my concerns is with salt and moisture getting trapped under the material. I've seen this done more often on the inside....but I like the idea. I wonder if the undercoating alone would do much. If I could knock down half the wind noise around the windshield I'd be pretty happy.

I did this plus foam in all of my wheel wells. Tremendous difference in noise since the body on frame construction = unstressed panels = thunder like a tympani over even small bumps.

Rear quarter panels are harder to get to (have to remove both seat rows to remove the interior panels) but also worth it.

Moisture under the material isn't a concern. You don't remove the paint of course, and you apply the mat when it's dry...

Yeah sorry about the big pics guys, i will fix it tomorroe at work

There is absolutely no concern abt corrosion with applying this. The underside of my wheel well liners were spotless and so were the areas that i applied the dampening material to. My truck has 65k on it too.

My main goal was to dampen those loud "booms" us Pathfinder owners get when hitting the smallest of bumps and also to quieten down the overall road noise.

Now the truck feels much more solid (and quiet), the material i applied is rated to very high temps and will likely never have problems.

In the rear, I removed all the interior trim panels that cover the rear wheel wells and applied it to the inside (pics coming) and took up the carpet and applied another 10sq. ft. to the floor pans.

Guys, this makes all the difference in the world. Also in the back the wheel well liners are much smaller. They were removed and undercoated and i found a few places to apply the dampening material inside the wheel well just like the front (just not as much.)

Overall I used about 40sq ft. of dampening material, a mixture of dynamite pro and stinger roadkill extreme.

Buy it from Amazon, it's much cheaper than getting it from the local stereo shop or best buy. I HIGHLY RECOMMEND THIS.

And driving on wet streets is virtually silent too.

Ship Fixer, I believe you are the guy that posted pics of yours as well. I had had this idea for a long time and after seeing your previous post I decided to do it myself.

Thanks for info. I personally think the bulk of the booming noise comes from the rear and probably where I'll start if I get into this project. What drove your decision on where to use which brand of material? I see 36sq ft of Stinger Pro on Amazon for $100.

Awesome work!

Yeah, i had already done the lift gate about a year ago, that alone made a difference.

Spot on with the 36sq ft from Amazon, i used that along with some dynamat pro i had left over from previous projects. They are both good quality and equally easy to work with. Actually they are a pleasure to install, it's kind of fun to do. Neither of these will melt in the summer heat or stink like tar since they are made for the automotive industry.

Thanks for posting all the info. I'll keep it in mind, although I guess I'm just used to noisy interiors. If I can get the damned door seals modded to work as they should, then I can decide if I should Dynamat or not. Seems like a lot of work to do the interior, and I know I would need a bunch of extra fasteners to replace the OEM ones that break when removing everything. I read through a few of the Amazon reviews & one person noted that it took almost 3 of the bulk packs ($300+) for their little Subaru. Wonder how much it would take for the Pathfinder. Still, interesting idea.

Yeah the fasteners are a problem anytime doing interior trim (and even the wheel liner clips all broke when i took them off) but they are a dime a dozen and you can pick them up at the hardware store now too on the fasteners isle.

I would never try and completely cover the entire interior, actually this has been a process i have been working on for almost a year. Front doors are then only thing left i would like to do.

On the Pathfinder, i'm guessing you could easily spend $5-600 in materials if you wanted to cover everything.
