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 desertcart. They do officially sell with Summit Racing but the prices are much higher. I decided to order from desertcart 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 desertcart and a 1ft by 1ft sample I got directly from Dynamat tech support, I confirmed the desertcart 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. Review: Great product - Worked well for headliner installation keeps a lot of heat and noise out sticks well too ## Features - Dynaliner uses heat blocking properties in a single layer of synthetic foam. combined with Dynamat, Dynaliner nearly doubles the total thermal resistance ability - Dynaliner is a soft, self-adhesive closed cell rubber with thousands of cells packed extremely close together, which gives the material near zero air infiltration occurrences - Provides excellent insulation for the roof, firewall, floor, quarter panels, doors, and even under the hood - What’s in the box: Dynaliner 1/2 in contains one 32 in x 54 in x 1/2 in roll - 100% Made in the USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001JT5NIU | | Best Sellers Rank | #91,141 in Automotive ( See Top 100 in Automotive ) #177 in Automobile Insulation | | Brand | Dynamat | | Brand Name | Dynamat | | Coverage | Insulation of various parts of the vehicle | | Customer Reviews | 4.7 out of 5 stars 274 Reviews | | Global Trade Identification Number | 00769103111036 | | Included Components | DYNAMAT-DYNAMIC CONTROLS | | Item Dimensions L x W | 137.2L x 81.3W centimeters | | Item Thickness | 1.3 Centimeters | | Item Type Name | ACCESSORIES | | Item thickness | 1.3 Centimeters | | Manufacturer | Dynamat | | Manufacturer Part Number | 11103 | | Manufacturer Warranty Description | LIMITED WARRANTY | | Material | Rubber | | Material Type | Rubber | | Model Number | 11103 | | Product dimensions | 137.2L x 81.3W centimeters | | Recommended Uses For Product | Automotive soundproofing and thermal insulation | | Recommended uses for product | Automotive soundproofing and thermal insulation | | UPC | 769103111036 | | Unit Count | 1 Count | ## Product Details - **Brand:** Dynamat - **Item Thickness:** 0.5 Inches - **Material:** Rubber - **Product Dimensions:** 54"L x 32"W - **Recommended Uses For Product:** Sound deadening and thermal insulation in car parts ## Images ![Dynamat 11103 Dynaliner 32" X 54" X 1/2" Thick Self-Adhesive Sound Deadener - Image 1](https://m.media-amazon.com/images/I/61HehFO4MyL.jpg) ![Dynamat 11103 Dynaliner 32" X 54" X 1/2" Thick Self-Adhesive Sound Deadener - Image 2](https://m.media-amazon.com/images/I/81PJ8FWxy+L.jpg) ![Dynamat 11103 Dynaliner 32" X 54" X 1/2" Thick Self-Adhesive Sound Deadener - Image 3](https://m.media-amazon.com/images/I/715+qo6g5mL.jpg) ![Dynamat 11103 Dynaliner 32" X 54" X 1/2" Thick Self-Adhesive Sound Deadener - Image 4](https://m.media-amazon.com/images/I/71+zm+oYNyL.jpg) ![Dynamat 11103 Dynaliner 32" X 54" X 1/2" Thick Self-Adhesive Sound Deadener - Image 5](https://m.media-amazon.com/images/I/81J2suBlJGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The genuine article, closed cell, worth it *by B***R on 29 November 2016* I've got an old diesel truck and it's very loud.
