DYNAMAT 11905 Hoodliner 32" x 54" x 3/4" Thick Self-Adhesive Sound Deadener – Made in USA

Used this on a 2008 Yamaha AR230 jet boat engine hatch. Cut down the sound from the engine by 60-70%! We can now actually have conversations with the engines running.

That it is a great product and it's easy to install with alot of adhesive grip. I am extremely pleased !

So far so good. Easy peel and stick. Used old liner as template. Need sharp razor knife and scissors. Only downside logo flakes off to easy when pressure is applied. Adequate stick when surface is cleaned and ready. Don't attempt on dirty surface.

Worked great!

This product worked extremely well. The stick of the adhesive is great and it forms well.

This is PERFECT for an RV doghouse/engine cover! I saw this mentioned in an RV forum and was about to buy a similar product that was thinner/cheaper but I decided to go with this since the price wasn’t that much difference but the thickness was much better with this product. We have a motor home and the engine cover is between the front seats. It gets VERY warm, especially during the summer months of travel and it’s always noisy, but we mainly really wanted the heart reduction properties. This came in the day of our trip and I decided to try to install it, it was really simple, cutting a piece and sticking it on, then trimming the edges. Our engine cover is an odd custom fiberglass shape, almost like a huge ice scoop. This still confirmed to the curves and edges really easily. It even stuck really well to the existing thin reflective material that was already in place with industrial glue. So the sticky backing is really strong! But most importantly, there is NO HEAT coming from the engine anymore! It’s amazing! I can feel the transition from the base of the engine cover where there is no dynamat, to the engine cover where I installed the dynamat and WOW! I would say there is easily 40° of heat difference at least. There is just zero heat coming from the engine into the cab now. This product is WAY better than I even hoped! I really feel like the engine noise is much better than before too, so that’s an added bonus for us as well! Highly highly recommend this especially for RV owners!

Put this in a 1999 Nissan Frontier. Always better to do something like this than start a car payment with something new.

I modified my 2001 Frontier with intake, header, and exhaust and was able to reduce the noise from the rear by installing FatMat (also a great product for the price) in the rear of the vehicle which worked beautifully, but the noise coming from the engine compartment was another issue. It was starting to become unbearable for short highway drives at 70MPH. In comes this hoodliner. The price was right on Amazon ($58 vs $80+ everywhere else), installation was a breeze (ensure the surface is clean prior to application), and the difference was amazing!!!!. I'd recommend this product to anyone that has modded their vehicle's intake system and those whose vehicles did not come or do not have a hoodliner. The only thing negative is that the white lettering flaked off as I was using my hand to apply the liner to the hood. I also need time to assess if the adhesive material maintains its bond to the hood. Only time came tell so expect a followup to this review.Onto the Fatmat: I purchased a roll from them 3 years ago for appox $80 and have covered all 4 doors on my 04 crv's w/ 2 layers, covered my crew cab frontier's: headliner, floor pan, 4 doors w/ 1 layer (I had already lined them with Dynamat which cost me about $100 for one layerof sound deading per two doors, you see the cost difference). behind and under the rear seat w/ 2 layers, and I still have enough material for the doors on my 300 ZX. I do not want to know how much that would have cost me if I would have used Dynamat throughout my vehicles. Dynamat brags that it is thicker than Fatmat and that maybe true, but their door kit goes for $80 and only covers 2 doors ( and that is a front door and the smaller back door and you have to be creative in reusing the leftover material from the front door). For $80 I was able to do the above, allping 2 layers where needed and I still have material left over. Just food for thought!
