I used the 1/8" thick Dynaliner in two areas of my 2016 Ford Transit Connect Cargo Van. I used it on the front driver and passenger doors over Dynamat Extreme. That's as much as I could get by with behind the door panel trim. That alone provides some degree of thermal barrier on the door panel as well as additional sound dampening. The second location I used it on is a metal bulkhead. The bulkhead had a vibration rattle at certain rpm's and poor road conditions. So I started with Dynamat Extreme on the backside of the bulkhead (the side in the cargo area) surrounding the perforated window in the center of the bulkhead. Then I applied 1/8" Dynaliner over the Dynamat. That totally eradicated the rattle. I have no regrets going the extra mile in expense and installation time by using Dynaliner throughout my Transit Connect. I used 1/2" Dynaliner on the roof, the two side slider & two rear doors and several body cavities. I used 1/4" Dynaliner on the window metal panels (where the glass windows normally would be). I used the 3/4" Hoodliner over Dynamat Extreme inside the engine hood. I would estimate the engine--which was already quiet from the factory--was about 20% quieter at idle speed. You'll benefit having both a thermal barrier and additional sound dampening using Dynaliner over Dynamat Extreme. Yes, it is worth it! Beware: purchase only from an authorized Dynamat vendor. Dynamat voids their warranty if purchased from an unauthorized d
Pros: Super easy to install. Further enhances sound deadening over using just Dynamat alone. Reduces thermal transfer of heat. Dynamat, Dynaliner and Hoodliner is the single best investment I've ever made on a new vehicle.
