oh and david idk what i was thinking but under the fender well sounds like a good idea! i was actually thinking of the backside of the actual fender....

i have rubberized undercoat in my fender wells.... do you guys think it will have problems adhering over it?

It works pretty well on the rubberized parts. I sprayed the entire underside of the car including the rubberized stuff. I was also thinking the backside of the fenders or on any unexposed surface.

And under the hood, you have to spray the stuff on pretty thick so "thinning" would be out. I put my hood liner back on to cover the Quiet Coat.

hmm...trying to find something to make my carbon hatch rattle less

think quietcoat would work on it or would b-quiet or similar be a better alternative?

I pulled my carpet and headliner out so I could swap them to black. Do you think doing the floor and top would make a big difference?

Thanks,
Jeff

Yes, most definitely. Those are two of the areas that give you great results. Do it!

David -

Thanks for sticking with this thread.

Long story short, I'm getting my engine rebuilt, and while its being done, get the car repainted and deaden the sound in the interior.

It would be easy for me to spray in the panels and up in the fender wells while the car is being repainted (panels off!).

I'll give this stuff a whirl and report back next year with a full write up!

Thanks again.

No problems. Do it and let us know how it works out.

Happy Holidays!

Just an FYI:

I used 100 sq ft of FATMAT in my FC. That's one layer and did the doors plus the entire floor pan from the firewall to the spare tire well. Someone earlier was asking for an estimate...

Alright so I found a box (36 sq. ft.) of Dynamat in my basement and I wanna shut up some rattles and noise in my vert. What are the primary areas that are best to cover? I sprayed sound deadener behind the seats and up a bit into the spare tire well, and there are no rattles there but it sounds like the doors are a bit. I've searched this thread a few times but can't find a straight answer.

If you have already gotten the spare tire area behind the seats in a vert, I would say next is the doors, unless you feel adventurous and want to rip up all of your carpet to do the floor.

Nice post, thanks, had too much rattling sound in the whole car

Btw anyone has rattling from the undercarriage from certain rpm range??

David Hayes

^ I did and it was my PPF (power plant frame). It had twisted and caused noise at low RPMs.

I bought a few gallons of "Lizard Skin" Sound control. It is a spray on application and makes it nice to get into all the "nooks and crannys". Although My car is not running to specifically tell road condition sounds and such i still got a eye opening experience. After tons of research i got gallons of this stuff and decided to go to town. I did the chassis (only interior wise, obviously) from the firewall, all the way to the trunk. I did inside the rear quarter panels, inside the wheels wells, pretty much every inch of the interior and inner structure of the car. After i completed this i decided to do a test. I had a few shells laying around that were in the exact same state as my car, so i set them side by side. The results were very surprising! Just sticking your head in the trunk area and talking was a noticable difference, tapping on the metal from the outside of the car was a astonishing. One sounds like a tin can the sounds like its concrete. So far everything seems like its going to work out and its going to reduce noise dramatically. At this point i HIGHLY recommend it.

This pretty much sums it up-
