Project sound insulation, Determined to get rid of some road noise Options

[GotToyota]

Alright guys, I decided to tackle a project similar to what a member on here did by getting rid of some noise with a carpeting material. I'm attempting the same thing, except with my door panels and rear panels. I went to Home Depot and bought a 6'x9' roll of carpet padding for $30, along with a can of 3M rubber and vinyl spray adhesive. I already tried to deaden the sound a bit by using some extra Dynamat I had, but it didn't help much at all. Spray the door panel on the areas where you will be placing the padding, then rip pieces to the size of your choice and place accordingly. WARNING: You might want to let these panels sit overnight, because the smell isn't too pleasant.

After I get everything finished I'll let you guys know how well this worked. I spent $40 in materials with tax, so it would be a pretty cheap solution to getting rid of some exterior road noise. Not the prettiest solution, but I feel it should help out greatly.

I tested the duct insulation myself, and found it's not closed-cell foam, so it will soak up water. However, it seems to dry out well.

Keep in mind the Celica already came with a felt pad underneath the carpet, under the rear seats, and attached to the underside of the trunk carpet.

Exactly. So as for the foil-backed insulation stuff, you should be good to go with normal use. I'm using it in my car now, and haven't had any problems with it whatsoever, which says a lot considering I'm in the pacific northwest and the ridiculous amount of rain we get here in the winter.

Edit: I just read the rest of the thread. I've got a '94, with basically no OEM upgrade options like power windows or upgraded sound system, etc. but I DO have the STOCK sound deadening stuff beneath the carpet. So it's not true that all 94-95s came w/out it.
