Well, I finally did it, I threw down for some Dyna Mat® "Extreme" plus some Original Dyna Mat® and did the whole inside floor/wheel wells and rear panels.
After having no carpet in the rig for years (spending two days hammer and chiseling up the factory sound deadening so I was able to get to metal for welding), I've decided to mute the noise.
My transmission access panel was not even bolted down, so noise and heat were just pouring in.
Let me say, this stuff is working so well, it's expensive but is worth it's weight in gold.
I had read a great thread on here which had a link to a gentleman who had performed an extensive test of pretty much all the popular name brand as well as hardware store products.
In my findings, there was quite a difference between Dyna Mat® Original and the Dyna Mat®t Extreme:
Dyna Mat® Original seems to be like an adhesive rubber membrane which unless applied with a heat gun and applied in conjunction with the Dyna Mat® 1" roller (good $8-10 investment) can be very labour intensive - side note, my BJ60 has 2 coats of POR 15 under 2 coats of Herculiner (not a smooth finish for adhesion) however, as you get more familiar with working this product and before your hands quit on you, you'll get it to stick.
Dyna Mat® Extreme was an absolute pleasure to work with, I had actually started with this product for my project and then purchased the Dyna Mat® Original for the rest of my project.
This Dyna Mat® Extreme has the feel of a pliable tar based product with a top sheet of foil to deflect heat - THIS STUFF IS STICKY!!! and is very accommodating when it comes to contours, keep in mind, if you thought paper cuts were annoying, think about the top sheet of foil slicing away at the tops of your fingers as you're applying this stuff.
First impressions:
The first session working with this stuff, I did the front section (just in front of the pedals to the rear of the front seats) - AND WOW, this seemed as if I was driving a different truck (notice how I did not say a new truck) this was a huge difference in noise and heat reduction I was super pleased, and each evening as I made time to apply more (Dyna Mat® Original in the rear section) the vehicle became less noisy from the inside.
My Fiancé has only known this truck to be a loud rat which always needed work, but as I do the work, this BJ60 is getting better with age.
Chuckles from the slow lane!
PS. I purchased a pack which contained 36 square feet of Dyna Mat® Extreme and a pack which contained 36 square feet of Dyna Mat® Original
PPS: The dashboard grab bar for the passenger is a nice stainless steel door handle from a civic centre.
