Installing Dynamat



I just completed installing dynamat extreme in a 67 coupe, I went in to the job not expecting much.
I was very surprised!
This stuff is just great, there is nothing negative to be said about it by me, other than its not cheap. But in this case, do to the ease of installation and the end result I feel well worth it. Installed a sheet on inside of inner door skin, some on the inner door panel (as it will fit nicely behind the panel and under the headliner ) , and the floors, wheel houses and two sheets on the roof, the difference in acoustics is dramatic, even closing the door it sounds like a heavy steel door now. I also used the jute on top of it. I am pretty sure this dynamat could be used under the 63-4 carpet also without any problems with fit.
I used 50 square feet, could have used another 10 or 20 but you really do not need to cover every square inch, for example, on the roof I used a 12" X 28" strip on each side, covering about 75% of each side. Thats all it took to do the job acoustically, but if you feel you want to close to 100% coverage, you will need closer to 70 square ft, by the way, there is no waste, no scraps, each trimmed piece is still usable somewhere!
Good Luck!

the dynamat is great stuff...get a golf ball and a tennis ball for the installation as you can simply roll it into the corners and contours of your interior, i have no experience with hush mat and i know the dynamat is expensive but the d-mat EXTREME is what i used....good luck

Have not tried the other product but if someone brings it to me I would try it and maybe think its better, but if I had to buy some today for my own car, I would buy the dynamat. I would like to see a comparison though, I suspect they may be very similar. It appears to be very similar to weatherwatch or similar roofing product.
In my smugness thinking that a couple of years ago I bought a roll of it at Home Depot, brought it home and then realized its only the first few inches of the edge that is no covered with roffing shingle granules.
Reaturned it.
Otherwise it appeared the same as this dynamat, maybe a bit thinner, just a LOT cheaper.
If it turns out its the same, must be even cheaper for them to produce it without the granules, put some foil on it , call it something else and presto, profit!

Ditto on the 3M adhesive. I have the part numbers at home, but alas, I'm still at work. If it is important I'll try to dig them up and post.
