does dynamat reduce road noise?

You can combat the rust if you use that underbody spray stuff BEFORE u use the spray on dampening.

Well I got it done. I ordered 2 rolls of Raamat and 13 yards of Ensolite. Stripped the interior out. Roof: One layer of the mat, one layer of the ensolite. Floor: Two layers of the mat, One layer of ensolite, and two layers up against the wheel-well area. Rear firewall: Two layers of the mat, One layer of the ensolite. (Trying to remember what I Put in these) Ext can Doors: 4 layers of the mat, 4+ layers of the ensolite inside the doors. 1 layer of the mat on the outside (metal directly behind the door panels) and 1 layer of the ensolite. Front doors: 4 layers of the mat, 4 (or 5?) layers of the ensolite inside the doors. 1 layer of ensolite to replace the vaporbarrier. Results? Was it worth the $500+ I spent?   Kind of. Did it help? Yes.   It helped with speeds especially between 30-50mph. 60+ it really had minimal effect. I believe the frequency of the tires resonate past this stuff.    NOW if I had all-terrain tires / street tires the truck would almost ride completely quiet, except for the hum of the engine.Mighty Hd
