Installing Dynamat into your Tri-Five Chevy

In your new car that you drive every day, it’s easy to get used to the quietness of your ride; from road noise to drivetrain, the sounds cars make are almost completely eliminated. Driving your Tri-Five, on the other hand, you're likely to realize what a huge difference there is between the quietness of the new cars and how loud they used to be. Fortunately, Dynamat is a product proven to reduce outside noise in your Tri-Five. Dynamat consist of self­ adhesive acoustic dampening material boned to an aluminum sheet that will help your Tri-Five to not sound like a tin can while driving on the road. And even better, Dynamat isn't just used to reduce outside noise; it also helps keep radio noise in the car and focused on the listener.

Before installing the Dynamat into your vehicle, you'll want to clean any surfaces that it will be used on. The cleaner the surface, the better the adhesion. A quick drying solvent will be the best option for pre­ installation cleaning.

Using a razor or scissors, cut the Dynamat pieces to size, so they will fit on your desired surfaces. If you are applying larger pieces, it is best to remove half of the release liner on the back and to work it down the section you are securing it to

Once the Dynamat is where you want it, use the Dynamat roller tool to apply it to all surfaces, using both the roller and the handle to work the Dynamat into the contour of the metal. Make sure you go over as much of the Dynamat as you can, as to achieve the best quality and long lasting adhesion possible. If there are air pockets in the material, poke holes in them with your razor knife to remove them, then go back over them with the roller. Fair warning, the adhesive is VERY strong.

You'll notice that Dynamat is applied to every square inch of the floor on the 2017 Street Rodder Road Tour '57 that is shown. Where more is definitely better, unless you after the maximum when it comes to sound dampening, this is not a necessity. It will serve the same purpose by doing large pieces in different sections of wherever you are going to cover.

If you're looking for more heat dampening capabilities than Dynamat has to offer, using Dynaliner in conjunction with your Dynamat is another option. Consisting of a different design of self-adhesive foam and installing the exact same way, it goes on over the Dynamat and helps keep the heat in during the winter and heat out during the summer. Just the same, Dynaliner will also help even more with sound dampening.
