I insulated with peel and seal (Home Depot, roofing area)

Worked good to reduce noise coming from the trunk area.

Does it leave any sort of musty scent or fumes after it dries? I remember when I redid my headliner in my '91 Cutlass, I used 3m adhesive and it always gave me a headache the whole rest of the time I owned that car.

I found this, he used duct insulation, what do you think of this?

OK, try this trick to find out exactly where any leakage may exist. Go to the local car wash (or your yard) and really soap down your car. Turn on your a/c full blast, and shut all the doors. Also, pop open that rear seat pass-through. Make sure this soapy water is HIGHLY soapy, and make sure all your door and window seals are wet down really good. You will be able to see bubbles form whereever air is leaking, and obviously the bigger bubbles will have a bigger impact on wind noise.

Hope this helps!

[quote="marquette97"]I had this same problem. Fortunantly my windsheild was pretty banged up from various sources so I was able to get a new one using my insurance. The noise problem was fixed after that.
