sound proofing the wagon

[michaedo]

After a couple weeks and a couple hundred miles I've come
to the realization that the wagon is waaayyy too noisy so
started down the path of trying to quiet the interior down
some. I priced Dynamat, picked myself up off the floor and
went looking for an alternative. Came across a product
called Peel & Seal, the real purpose of this stuff is roofing
repair but it seems like it will fit the bill at about 20% the
cost of Dynamat. Got it at Lowe's 6"X25' roll for 14 bucks.
Was able to do the storage area right behind the rear
axle with one roll. Will be doing the rear seat area and
inside the doors in a couple days. I'll let you know if I
hear, (or don't hear) a difference in db.

If you could find somewone with a DB meter and have them let you borrow it, we could be all scientific about the sound attenuation with various materials. I did a science project about that in school a few years back, soo...

[LeftLaneGuy]

Heh! Yes, they're ALL noisy.. especially once you put in exhaust, etc..

I took my wagon to a Line-X place, stripped-out of course, (just the driver's seat) and had it sprayed with bedliner.

Put the new carpet in, and the rest 2 days later...

One word: Incredible!

I imagine you could do the same thing yourself with that roll-on stuff you can buy @ the parts store..

Dynamat is awesome, but not really meant for complete coverage. More for small areas that 'drum' alot of noise like inside the door.

Just install another muffler, it'll do the same thing but a whole lot cheaper.

Check out the thread above, post #5. I used this same material on my '73 GT, and really liked they way it quieted down the interior. I've never used Dynamat, so I can't compare the two, but i really liked the price!

Hi there Chris,
Ha, yeah, had the muffler installed before it even ran. Magna-flow.
The noise is pretty much everything else. Installed poly bushings
everywhere while it was laid up, that sure don't help with the
road noise. I feel like I'm riding a motorcycle 'cept with no wind
whippin' through the hair. (Well, not much hair to have the wind
whipping through anyway.) I guess noise is part of the
enjoyment of Opeling anyway.

[michaedo]

Oops, well, it looks like it's all been covered in the last year.
Sorry, I thought I was on to something and wanted to spread
the word.
Don.

Use the same link wolfmann posted above and look at post 11 about Lizardskin. That is what we used on our v8 opel.

Check my album . I've just done what your looking at.I used dynamat around the transmission & the roofing stuff on everything else.Also used a spray that deactivates any rust before I put anything down then the sound deadeners ,then the underlay & new carpet from OGTS..Looks & really deadens the sound.Good luck

I insulated my GT with B-Quiet Ultimate. B-Quiet sound deadening materials - B-Quiet Ultimate - Better than Dynamat!! brownbread
It made a huge difference. I know that some other members used that material as well.
I also put it inside the doors. The door now closes with a confident "thud" instead of "clonk!"
