### ⭐⭐⭐⭐⭐ Great Stuff!
*by T***R on November 1, 2014*

Damplifier (from Second Skin) + Dynaliner make for a great combination. Dynamat is far messier to install than Damplifier, but the Second Skin version of closed-cell foam liner is not self-adhesive. Thus the Damplifier/Dyanaliner combo, though not exactly cheap, makes for the best DIY install.For doors in particular, don't laze out and simply use big, single sheets to cover the "middle" of the door. (One often sees this in photos of 'professional' installs). Though it requires lots of small pieces because of limited access, take the time to put Damplifier on the outer door skin itself. 100% coverage with this is not necessary, but I do every surface that's reachable. Any material that's not securely stuck to a metal surface is wasted. IMO, it's also very important to treat the crash beams within the doors - they can act as tuning forks and contribute to noise and poor door speaker response. Doing this will take ~50% more material than one would guess by the expose door surface area, but it's worth it. The Dynaliner is stuck over the Damplifier and is much easier because it's far more flexible. By turning the doors into an almost-proper speaker box, stereo quality, especially in the bass, and especially at mid to high volumes is *greatly* improved. It's probably the cheapest sound system upgrade around.BTW, while the doors are opened, I also spray the corner where the outer door skin meets the door frame with waterproof synthetic grease. That corner is a great place for rust to start. Also, avoid covering that edge with soundproofing material - do not give water a place to be trapped and also make sure not to cover the drains at the bottom for the same reason.The 1/4" version of Dynaliner, when you have the clearance to use it, seems noticeably more effective than the 1/8" version. However, the 1/8" thick stuff is the best rattle reducer I've yet found for those annoying rattles coming from interfaces between plastic trim pieces and where the plastic trim is not tightly held in place against metal.Don't confuse this stuff with typical open-cell foam used for furniture cushions! It is useless as a sound deadening or blocking material. Get the real McCoy.

### ⭐⭐⭐⭐⭐ The genuine article, closed cell, worth it
*by B***R on November 29, 2016*

I've got an old diesel truck and it's very loud. I thoroughly researched a number of products to line the hood and decided to stick with the big brand Dynamat. There are cheaper solutions from the hardware store if you just need a little foam padding, but if you want the best, buy this.Generally quality grades go (from best to worst): Aviation, marine, automotive, consumer/home. This stuff is made for cars and will outperform nearly any home-use product like foam for an attic etc.I contacted Dynamat and they officially do not sell on Amazon. They do officially sell with Summit Racing but the prices are much higher. I decided to order from Amazon directly and check the product. There's a lot of knock-off Dynamat online from less reputable vendors (Ebay etc). While the knock off stuff looks the same, it is not always closed-cell. You want closed cell foam for any exterior installation. Open cell foam will soak up water like a sponge and weigh a ton!Using the roll I got from Amazon and a 1ft by 1ft sample I got directly from Dynamat tech support, I confirmed the Amazon listed product I received was genuine. I even went so far as to weigh each square on a postage scale, soak them in water, and then weigh them again. Neither absorbed any water. The weight was the same after soaking.Installation was straight forward enough. Measure twice, or three times, cut once. I was able to cut the Dynaliner with a good pair of kitchen sheers and this seemed to work much better than box cutters. In order to ensure proper sizing, I cut out templates using construction paper, taped them in place on my hood using painters tape, and then traced them onto the Dynaliner. Be sure to get every nook and cranny filled. You want to ensure the liner is adhered to the entire surface with no air bubbles. To achieve this either start at one side and move to the other SLOWLY, or start in the middle and work out. I went side to side because I could trim off any excess when I hit the final edge. Peel the backing away as you go vs all at once (unless the size piece you are applying is small) because the adhesive is very sticky and it will be hard to keep it from sticking in the wrong places once you remove the backing.I did not use w DB meter to measure the sound drop in my interior but it is significant. I will report back in a year or 2 on durability but so far it looks great, and really cuts down the noise.

### ⭐⭐⭐⭐⭐ Dynamat Dynaliner
*by A***1 on January 22, 2025*

This was installed in the roof of a 1969 Camaro we are restoring. The body man that replaced the roof said this was the best brand to use. Dynamat was installed first then the dynaliner. The size of the dynaliner sheet worked well so that seams are hidden by the roof struts. The dynaliner and dynamat are both between the inner supports and roof panel creating a solid roof damper.
