Installing Dynamat on doors: OK to leave the black glue?
 

I am attempting to install Dynamat for the first time in my doors, and I removed the plastic moisture barrier per the instructions, but the adhesive left on the door is so soft and sticky that it's a pain in the ass to try and remove. The more I try to scrub it off (after using some adhesive remover) the more it seems that I'm just spreading it around. Is it OK to just put the Dynamat over the adhesive?

Yup, just leave it. Butyl sticks to everything and so does dynamat.

:happy0180: Thanks!

Let us know if it takes away that terrible rattle of too much bass.

HUGE DIFFERENCE!!!

I did some selective Dynamat around the speakers in the doors and now that all the rattles keep popping up I will be adding a full job to my to do list.

I just did this on my BRZ and the doors are now rock solid. Next up is that rattling rear :sigh:

Are there any instructions for doing a full dynamat on a brz?

Instructions

Strip everything out that bolts or snaps in place
Place Dynamat on metal
Reinstall everything that bolts or snaps in place

Needs pics.

can you link what you ordered? i've been looking at this:

Dynamat Xtreme Door Kit 10435
Xtreme Door Sound Dampening Kit with Four 12" x 36" Pieces
http://www.newegg.com/Product/Produc...9SIA15Y0AE3155

would that be enough?

I'm curious about the same thing in case i went for a full dynamat door job.

I was planning on just putting dynamat around the speakers and some on the outer door skin. Then installing dynaliner over the doors between the inner door skin and the door panel. That should kill the rattles and help the audio quality a bit shouldn't it?

Guys, guys, guys!

Dynamat is just a brand name product for CLD. If you are buying Dynamat, I sincerely hope you have considered at least one of the handful of other brands out there that perform the same as, if not better than, Dynamat for a (sometimes MUCH) lower price.

I'm installing GTMAT right now on my FRS. 25ft^2 of GTMAT Ultra (80mil) cost me $60 shipped & no tax from Amazon.[ame="http://www.amazon.com/gp/product/B008L3ZRZQ/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1"]link[/ame] The kit also comes with a little roller than really helps with installation (you need to buy it separate with Dynamat - another $15).

The 25ft^2 should be enough to make a difference.... installed in the two doors, the trunk lid, and some light use under the spare tire... it really all depends on how much weight you want to add to a light sports car. For the doors, I have about 30% coverage on the outer skin, and 30% coverage on the inner skin (focused around the 6.5" woofer). Websites on this stuff says the important thing (besides eliminating rattles) is to separate the air from the front of the woofer from the air behind the speaker. That's why I bought some "For Rent" signs and duct-taped the few holes that exist on the inner skin. I'm still looking for something similar to Dynaliner for between the inner skin and the door card. Be careful not to overdo the trunk liner or else the auto trunk release may not open the trunk cause its too heavy. Make sure you also take care of the rear license plate/frame cause that is a very common source of rattles.

Here's a "work-in-progress" photo from Saturday.... I can post some more of the finished product later.
