Guys, if I may: I am a Vibration Analyst, among others and I believe the way Dynamat works is not by making the "panels more rigid", is rubber - and that is elastic, not rigid, but by adding mass, hence lowering the natural frequency response of the panels. In other words, the panels will vibrate less to the music or other sources of vibrations, obviously depending on the frequency that excites them. Sound will also get "bogged" trying to penetrate the rubber lining, adding to sound proofing.
such an overkill. dynamat doesnt soundproof. it makes panels sound more rigid, theres so need to cover every bit of the panel with it. what stops the sound is dynaliner and thats gotta have complete covarage. but top job installing it so neat. its tricky to work with and i found using a heatgun made it much easier
i would seriously be concerned if water entered the cab and got stuck under the mats and won't be able to air dry. theres a strong potential for rusting and corrosion if it was sea water. if the interior happened to be flooded its looks like an impossible task to get under the mat to properly dry the water. just my opinion bases on observation of the installation.
I think you would find though that water would really have trouble getting between the metal and the dynamat because it is stuck down so solidly and evenly all over ..... to be honest though, I don't think I would spend the money because as psy06 mentioned, it is overkill. I think you really are paying for the name as I've seen big car audio system, like competition level SPL monsters, and whilst it does make the panels a little more rigid to stop vibrations, the cost to benefit is a little higher when there's cheaper options on the market.

How much Dynamat was used to complete the LC79?
great video - as somebody who has just bought a 76 series wagon, do you recon this was worth it?
Can you show the noise measure before and after?
I am ready to pay for it if you agree to come to sudan and do this in my toyota

Fast workers will take my car to them ha ha
