About the Dynamat Hoodliner
Dress up your engine compartment with a Dynamat Hoodliner. The 3/4"-thick "Sound Soaker" foam absorbs up to 87% of your engine noise, delivering a quieter listening experience in your vehicle. The reinforced aluminum skin creates a water/oil barrier that reflects 97% of radiant heat, protecting your hood's finish.
Note: We've gotten great results using Dynamat Hoodliner by itself on a variety of vehicles. For engine compartments with high heat or noise levels, Dynamat recommends putting down a layer of Dynamat Xtreme first, and installing Hoodliner over it. You apply Dynamat Hoodliner to your hood's flat panel surfaces (not the ribs) — the packet includes one 55-1/2" x 32-1/2" sheet (12 square feet), plenty for just about any hood. Warranty: 60 days.

What's in the box:
- One sheet of Urethane foam (has an acrylic adhesive and pull off liner on one side and a reflective aluminized surface on the other side)
Dynamat Hoodliner reviews
Impressive quality out of the box. I don't have any measurements for how much engine noise was reduced after installation, but the car does feel quieter. I installed this on a Lexus sedan, which was already quiet compared to most cars. Some folks complained about the difficulty of re-arranging the hood liner once the adhesive had caught. Here's a solo installation tip: Once you cut the hood liner to size (which is easily enough done with scissors), lay the hood liner on top of the engine block in the EXACT location where it will be when the hood is closed. Remove the protective layer from the sticky backing (which should be on top). Then just close the hood all the way latched. When you open the hood again, enough contact points should have made contact so that the hood liner is now stuck to the hood in the right place. Use your hands to press across the liner against the interior of the hood so that it's sticking in all places.

Works great! I'm on the interstate a lot! And it reduces engine noise really well. I also put dynamat extreme on before hand can tell a big difference
Pros: Very easy to put on, works as described!

Worked as it states in description.
Pros: Quieter engine noise
Cons: Once the sticky backing hits a surface it is stuck. Would be nice if the adhesive was pressure activated

This product is awesome. This is my second purchase of this product and it really does as advertised. May even be better than the manufacture's hood liner. I would highly recommend it to anyone. it surely does worth the money.
Pros: Can be cleaned easily and it stays in place. reduces engine noise, keeps the hood cool and saves the paint.
Cons: It is not removable or transferable once its applied.

Product looked well-made, but was unable to install due to temperatures of only 45°F. The backing glue would not stick to my hood at these temperatures. Still waiting for warmer temperatures, or may have to unbolt my hood and bring it inside to warm up on my TDI sport wagon and then install it.
Pros: Easy to cut.
Cons: Backing adhesive very temperature sensitive meaning will not stick in cold weather.

I wanted to make my 97 Saab Quieter so I could hear quiet passages of music. I also did not want to throw a lot of money at a car that wouldn't get more than $2500 if it was totaled. I used it without the Dynamat extreme as Dynamat recommended. The install is fine and the car seems quiter

I have a couple of quibbles with this product. First, at 5' x 3', I'm not sure it would cover most underhoods, much less mine which is not overly-large. Second, on the box it reads 'for optimal results, install over (a layer of) Dynamat Xtreme', which I did not have lying around the workshop. This was not hinted at either in the advertisement or in my pre-order tech support call. This is misleading and unhelpful. Of course I want 'optimal results', but don't necessarily want to pay more for it, or wait for the Dynamat Xtreme to arrive. So, disappointing on three counts, and this is before I find out if the product even works!

Purchased for a manual transmission Subaru, where the mid-frequency noise from the engine at higher revs was just a bit annoying. I was skeptical whether the Hoodliner would cut it much without doing additional sound deadening on the floor and firewall. It actually worked far better than I had expected. Did a fantastic job of cutting engine noise across the spectrum and improved the listening (and driving!) experience. Well worth it.

The Dynamat Hoodliner works exactly as advertised. After driving in town all day, the hood isn't even slightly warm! Great product and installation was very straightforward...just peel and stick. Highly recommended product.

More details on the Dynamat Hoodliner
Materials: The Hoodliner consists of three separate layers. The first layer is a 1 mil reinforced, Aluminized heat reflector and water/oil barrier. "Sound Soaker" Urethane acoustic foam forms the middle layer. The third layer is a super aggressive 4 mil acrylic adhesive with an "EZ Peel" release liner.
Benefits: The Hoodliner has the following benefits:
- Absorbs engine noise
- Stops hood paint failure
- Improves the look of the engine compartment
- Tough Urethane foam is easy to cut
- Reflects 97% of radiant heat and insulates
- EZ Peel-N-Stick application makes for an easy installation
Instructions: For proper installation, follow these instructions:
- Thoroughly clean each mounting surface with a quick-drying solvent that is residue free (Isopropyl Alcohol, Acetone or Lacquer thinner), removing any grease, dirt, oil, wax, moisture or rust. With the surface clean and smooth, a permanent bond is assured.
- Using a razor knife or scissors, cut to the desired shape and size. Remove release liner. On large area applications, remove only a portion (8-10 inches) of release liner at a time, working your way down and across the panel in sections.
- Heating the panel surface you are mounting to before applying the material is recommended to insure proper adhesion. Also, heating the Hoodliner will make the glue stickier. This will keep the Hoodliner in full contact with the panel maximizing material efficiency.
- Apply the Hoodliner to the panel surface, starting at the top corner and working your way down and across, pressing the material into place as you go. With a roller tool, burnish the Hoodliner to the surface. Starting from the center, work it into all contours of the panel. Even if it's a smooth panel, rolling the material will insure lasting adhesion and full contact with the panel surface removing any trapped air.
