Hey i'm going to install some sound deadening mats in my 1999 F150 and i was wondering if this stuff looks any good, or if i should go with dynomat, its just that this stuff is alot cheaper than dynomat. If it isnt any suggestions where to get dynomat. I dont mind paying for quality things but i do like to save as much money as possible. http://www.partsexpress.com/pe/showd...number=268-035

 

I think the Dynomat is to high to start with. Some how people think highier price means better.

You can use 3M adhesive and rubber mate and get the same results. The ones you pointed out are .050 thick which is damn good for the purpose you have in mind. I also spray under coating in all the cracks and areas that do not require mates, Since I got the panels off and it takes just a few extra mins. to apply. Also it is cheap for a few cans of the stuff.

 

It's Dynamat, not Dynomat ( www.dynamat.com ).

Dynamat Xtreme is very expensive if you buy it retail. However, you can get a "door kit" on Ebay for around $50 delivered which is enough to cover two doors. A door kit consists of four 12"x36" sheets. I would stick to Dynamat since it is a very popular and well proven material for sound damping. The stuff you linked to appears similar but lacks Dynamat's foil backing and it is also not as thick (0.07" vs 0.05").

Spray undercoating would not be nearly as effective as Dynamat or any similar sound damping material since it is not nearly as thick. Also, applying a rubber mat with adhesive to a body panel would only be effective if the surface is completely flat and smooth, which most body panels are not. Dynamat or similar damping materials are very pliable and can better conform to surface irregularities that you encounter on most body panels in a vehicle.

I used Dynamat Xtreme on both my doors and it greatly reduced door panel vibrations due to the door speakers. It also greatly reduced the road noise coming through the doors. As an added benefit, the doors now close shut with a solid "thunk," similar to a luxury car. A pic can be seen on my homepage...

There are also many materials that are similar to Dynamat Xtreme and are said to be just as good but cheaper. In my online research on damping materials, the following appears to be a highly regarded alternative...

I bought my Dynamat kits off of eBay for a fairly reasonable price. And as was already mentioned, the spray is also a worthwhile investment.

If you're not sure about the cheap stuff you're considering, then why not just call up a place that does car audio installation and get their opinion?

 

Ok thanks everybody i think im going to buy a couple door kits of dyn*a*mat, and a couple cans of the spray for areas i cant put the mats. Thanks guys for all your input!!

 

danger_ranger_dude,

If your still researching try this site:

http://www.fatmat.com/

I bought the 100 sq ft roll (fatpak) for my f150 and did the doors, the back panel (behind the rear seats) and the floor. I removed all of the plastic moulding, the seats and the floor mat. The results were very impressive. In addition to improving stereo sound and reducing outside noise intrusion it also helps insulate the truck from outside temps.

Also in the cab of my little toyota RV I used the spray on stuff (sold as rubberized undercoating) in combination with a very thick carpet pad under the very thin floormat. This worked well but the carpet pad is a bit thick.

On my wife's Tribute I'm going to try the fatmat in conjunction with multiple coats of the spray on stuff. I'll use the spray on the areas where it's difficult to roll on the fatmat.

Tips:

If you're going to do a lot get some good mechanics gloves or the like- the sheet metal can truly be razor sharp.

Use blue painters tape over any holes in the panels you want uncovered. Then after applying the product simply cut an outline around the hole and the tape peels up easily exposing a clean hole. Great for the holes where panels clips and wiring harnesses attach.

If you use the spray on get the paintable stuff- usually a $1 or 2 more than the nonpaintable. But it dries and the other stuff stays an oily mess.

Good luck.
Tim

Hey Man I would have a look at a product called brown paper its fairly new but it the cats *** for deadening materials I was in the high end car stereo biz for fifteen years but I stil keep on top of whats going on out there. Oh ya don't buy it from ebay because he a scammer , he sells something from homedepot that kinda looks like it but its only about a quarter of the thickness and I know this because hes from around regina here somewhere-- rock on!

 

Yea the Home Depot Audio section draws a crowd.

 

Just got done applying a product called Peal & Seal. Found it at Lowes. Did it in two stages,doors,floor and back wall this summer and the roof last week. What a difference! Sounds like a new truck. She's 1987 Custom I bought new. Slowely upgrading her as time and money run together. Got a carpet coming from JC Whitney and will put a second layer of P&S then install the carpet. Peal & Seal is a roofing product consisting of sticky rubberised asphalt backed foil. I worried about it smelling but no problems yet, just a much quieter truck. Anyway, my experience. Good luck, gresebaul

 

The success of using Peel and Seal for sound damping appears to be mixed. Some people have no problems with using it, while others have had very bad experiences. See this thread for a heated discussion on this subject...

yeah this stuff is made from the same people that made the brown bread stuff. It looks pretty legit, and its shipped from canada so its not the guy thats near you. Heres the link, if anybody knows of any problems with this company, or have a better/lower costing stuff thats just as effective please tell me. Thanks like always everybody here has helped alot. This stuff should be alot better than the stuff i was origionaly thinking of buying. http://www.b-quiet.com/brownbread.html
heres the testing they did http://www.b-quiet.com/images/bb_page3.jpg
Heres the acoustic loss factor.
Acoustic Loss Factor ASTM E756 @ 200 Hz:
0.23 @ +0C (+32F)
0.26 @ +10C (+50F)
0.39 @ +20C (+68F)
0.32 @ +30C (+86F)
0.24 @ +40C (+104F)
This is the dynamat extreme acoustic loss factor.
Acoustic Loss Factor ASTM E756 @ 200 Hz:
0.24 @ +0C (+32F)
0.26 @ +10C (+50F)
0.42 @ +20C (+68F)
0.26 @ +30C (+86F)
0.19 @ +40C (+104F)

 

Oh yeah not trying to bash on anyone, but peel & seal is inconsistent in its stickiness, and heat resistance, i've looked into this, and as a floor application, if you want to go inexpensively its ok, but it doesnt perform very well on vertical places, or basically anywhere it needs to really stick. Some people get good batches and it sticks forever, but some get bad batches and it falls like humpty dumpty off the wall. You get what you pay for, but i can understand being broke.(or people who like to save their money for something else if its not all that important) THIS IS THE INFO I FOUND ON kontai69'S LINK. I HAVE NO PERSONAL OPINION, BUT WANTED TO SAVE YOU THE TIME READING IT ALL.

 

Sorry man it is brown bread I was talking about i don't know why the hell I thinking paper for.
