Dynamat questions.

[jayl]

1. Do I need to use a roller for applying dynamat?

2. Do I need to use a heat gun for applying dynamat?

3. To be sure, any wires that I run should go over the dynamat right?

I am thinking the correct way to install dynamat after the surface is clean...

- stick dynamat then use a roller / heat gun to get it to stick on the trunk fully
- remove air pockets

Please let me know if there is something I am missing... also if there is a way to do the install without the use of a roller or heat gun please advise..

I do not have a place where i can plug in a heat gun near the car.. I was thinking of using an inverter.. Also instead of the roller I am thinking of using a rubber maillot.

Thanks,

use Hush Mat brand sound damping, it is way nicer to install, no heat gun needed.

I have already purchased Dynamat... just need to do the install...

WHen i used dynamat it was sticky enough that i didnt need heat gun. Roller helps but using your hands to rub it down works too. for me, Since I new I wasnt going to take the wires out i dynamated over the wires.

Only use dynamat extreme with the foil backing. It's butyl based and goes on real easy without a heat gun. Buy a cheap plastic roller from the wallpaper section at a hardware store. Don't use the regular brown dynamat, especially for the trunk lid or vertical surfaces. This is asphalt based, stinks real bad in the heat and will likely fall of over time.

the only tools i recommend needed for dynamat is a decent utility knive, large scissors, and a roller. dont cheap out on the roller as that is your primary tool to get the material to adhere properly.

insufficent adhesion (air bubbles and voids) will degrade the performance of your dynamat dramatically.

GL!

awesome thanks everyone for the responses...

I am thinking i am all set tools wise...

just cant decide if I should run the wire under dynamat or over... I am leaning towards under for now... since i dont see a need to remove them.. if they go bad they will just have to stay trapped!! and new ones will run over the dynamat. please let me know if you see a big problem with this.

The wires that will be under the dynamat will be: RCA for rearview camera, constant power for the same.. and rear speaker wire.

One more question regarding heating the dynamat...would it be a problem if I was to heat it a little inside and then take it to the car ? would it go "bad" ?

Thanks for the replies from earlier...

[kenchan]

i would run the wires OVER the dynamt to minmize potential voids...unless it's super thin wires like your reverse light wire or something for your backup camera.

then you can use foil tape (hardwarestore) and mount your wire onto the dynamat.

[jayl]

if the wires are over the dynamat... whats the best way to hold it down so they dont make any noise...

[90 ST]

you can always cut strips of mat to use as "tape" to hold wires down, but i've never really heard of wires rattling.

[jayl]

thanks 90 ST.

i did the full trunk thanks to all that answered my questions it was big help...

once last question... I am installing rear speakers... should I put dynamet behind the rear speakers? It seems like it might be a pain to do..

Thanks,

[90 ST]

I wouldn't bother with rears, but if you are, yes, if you can get in behind to do it.

ok out of curiosity, if i can follow this up with some more.

What is the best material to use? Im looking for something that is thinner but yet works better (good ratio)

Also about how much would I need to attempt the entire hatch area + cabin area (behind seats, under seats + door)

Thanks!

[jayl]

from my current experience i used the 9 sheet extreme dynamat pack... and I think if I wanted to do the cabin area also I would need about 5 more sheets my guess?..'

and make sure you have a lot of time and patience to do this...

and a fan... it can get super hot in there!
